arm64: exec: Adjust affinity for compat tasks with mismatched 32-bit EL0
When exec'ing a 32-bit task on a system with mismatched support for
32-bit EL0, try to ensure that it starts life on a CPU that can actually
run it.
Similarly, when exec'ing a 64-bit task on such a system, try to restore
the old affinity mask if it was previously restricted.
