cpu-exec.c: Allow disabling of IRQs on ARM Cortex-M CPUs

Correct an error in the logic for deciding whether we can
take an IRQ interrupt which meant that on M profile cores
it was never possible to disable them.

The design here is still bogus in that M profile doesn't
have separate "IRQ" and "FIQ", which are an A/R profile
concept; we should ideally implement the proper priority
based scheme.
