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
