[IA64] perfmon: make pfm_sysctl a global, and other cleanup

- make pfm_sysctl a global such that it is possible
  to enable/disable debug printk in sampling formats
  using PFM_DEBUG.

- remove unused pfm_debug_var variable

- fix a bug in pfm_handle_work where an BUG_ON() could
  be triggered. There is a path where pfm_handle_work()
  can be called with interrupts enabled, i.e., when
  TIF_NEED_RESCHED is set. The fix correct the masking
  and unmasking of interrupts in pfm_handle_work() such
  that we restore the interrupt mask as it was upon entry.
