      Analysis of the stats, profile, the code, and the annotated profile indicate:
       - All of the overflow interrupts (one per packet overflow) are
         serviced on CPU0 with no mitigation on the frequency.
       - All of the receive interrupts are being serviced by CPU0.  (That is
         the way truescale.cmds statically allocates the kctx IRQs to CPU)
       - The code is spending all of its time servicing QIB_I_C_ERROR
         RcvEgrFullErr interrupts on CPU0, starving the packet receive
         processing.
       - The decode_err routine is very inefficient, using a printf variant
         to format a "%s" and continues to loop when the errs mask has been
         cleared.
       - Both qib_7322intr and handle_7322_errors read pci registers, which
         is very inefficient.
      
      The fix does the following:
       - Adds a tasklet to service QIB_I_C_ERROR
       - Replaces the very inefficient scnprintf() with a memcpy().  A field
         is added to qib_hwerror_msgs to save the sizeof("string") at
         compile time so that a strlen is not needed during err_decode().
       - The most frequent errors (Overflows) are serviced first to exit the
         loop as early as possible.
       - The loop now exits as soon as the errs mask is clear rather than
         fruitlessly looping through the msp array.
      
      With this fix the performance changes to:
      
          ------------------------------------------------------------------
           #bytes     #iterations    BW peak[MB/sec]    BW average[MB/sec]
           1048576   5000           2990.64            2941.35
          ------------------------------------------------------------------
      
      During testing of the error handling overflow patch, it was determined
      that some CPU's were slower when servicing both overflow and receive
      interrupts on CPU0 with different MSI interrupt vectors.
      
      This patch adds an option (krcvq01_no_msi) to not use a dedicated MSI
      interrupt for kctx's < 2 and to service them on the default interrupt.
      For some CPUs, the cost of the interrupt enter/exit is more costly
      than then the additional PCI read in the default handler.
