KVM: remove isr_ack logic from PIC

isr_ack logic was added by 32d4fe34e3 to avoid unnecessary IPIs. Back
then it made sense, but now the code checks that vcpu is ready to accept
interrupt before sending IPI, so this logic is no longer needed. The
patch removes it.

Fixes a regression with Debian/Hurd.
