mutex-debug: check mutex magic before owner

Currently, the mutex debug code checks the lock->owner before lock->magic, so
a corrupt mutex will most likely result in failing the owner check, rather
than the magic check.

This change to debug_mutex_unlock does the magic check first, so
we have a better idea of what breaks.
