slub: Fix signedness warnings
The bit-ops routines require its arg to be a pointer to unsigned long.
This leads sparse to complain about different signedness as follows:
mm/slub.c:2425:49: warning: incorrect type in argument 2 (different signedness)
mm/slub.c:2425:49: expected unsigned long volatile *addr
mm/slub.c:2425:49: got long *map
