locks: plug warnings about unitialized variables
They only showed up after I redefined LOCKSTAT_ENABLED to 0.
doing_lockprof in mutex.c is a real (but harmless) bug. Should the
value be non-zero it will do checks for lock profiling which would
otherwise be skipped.
state in rwlock.c is a wart from the compiler, the value can't be
used if lock profiling is not enabled.
