target/arm: Raise only one interrupt in arm_cpu_exec_interrupt

The fall through organization of this function meant that we
would raise an interrupt, then might overwrite that with another.
Since interrupt prioritization is IMPLEMENTATION DEFINED, we
can recognize these in any order we choose.

Unify the code to raise the interrupt in a block at the end.
