Log Message:
heartbeat(9): Move panicstr check into the IPI itself.
We can't return early from defibrillate because the IPI may have yet
to run -- we can't return until the other CPU is definitely done
using the ipi_msg_t we created on the stack.
We should avoid calling panic again on the patient CPU in case it was
already in the middle of a panic, so that we don't re-enter panic
while, e.g., trying to print a stack trace.
Sprinkle some comments.
