v2 e1000: Neaten e1000_dump function 

Use pr_<level> for printk
Use temporary instead of multiple pr_conts
Coalesce formats.

Save a few bytes of object code too:

$ size drivers/net/ethernet/intel/e1000/e1000_main.o*
   text	   data	    bss	    dec	    hex	filename
  60507	    369	  14120	  74996	  124f4

  60717	    369	  14176	  75262	  125fe
drivers/net/ethernet/intel/e1000/e1000_main.o.old

Removed printing of pktdata.
