Subject: [PATCH] rt: fix a build error on locking-selftest.c

Fix a build error while rt mutexes selftests:

lib/locking-selftest.c: In function ‘dotest’:
lib/locking-selftest.c:951: erreur: incompatible types in initialization
lib/locking-selftest.c:1003: erreur: incompatible types in assignment

lock_count is of type atomic_t.
