[IA64] MCA recovery improvements

Jack Steiner uncovered some opportunities for improvement in
the MCA recovery code.

  1) Set bsp to save registers on the kernel stack.
  2) Disable interrupts while in the MCA recovery code.
  3) Change the way the user process is killed, to avoid
     a panic in schedule.

Testing shows that these changes make the recovery code much
more reliable with the 2.6.12 kernel.
