The pending IPA interrupts are checked by ipa_isr_thread(), and
interrupts are processed only if an enabled interrupt has a
condition pending. But ipa_interrupt_process_all() now makes the
same check, so the one in ipa_isr_thread() can just be skipped.
Also in ipa_isr_thread(), any interrupt conditions pending which are
not enabled are cleared. Here too, ipa_interrupt_process_all() now
clears such excess interrupt conditions, so ipa_isr_thread() doesn't
have to.
