[IA64] minor irq handler cleanups

- remove unused 'irq' argument from pfm_do_interrupt_handler()

- remove pointless cast to void*

- add KERN_xxx prefix to printk()

- remove braces around singleton C statement

- in tioce_provider.c, start tioce_dma_consistent() and
  tioce_error_intr_handler() function declarations in column 0

This change's main purpose is to prepare for the patchset in
jgarzik/misc-2.6.git#irq-remove, that explores removal of the
never-used 'irq' argument in each interrupt handler.
