lock debug: sit tight when we are already in a panic

in:

  > http://bugzilla.kernel.org/show_bug.cgi?id=11543

The panic code called the kexec code which called mutex_trylock() which
called spin_lock_mutex() which then stupidly went and blurted a load of
debug stuff because of in_interrupt().

Keep the lock debug code from escallating an already crappy situation.
