kernel/groups.c: fix integer overflow in groups_search
commit 1c24de60e50fb19b94d94225458da17c720f0729 upstream.
gid_t is a unsigned int. If group_info contains a gid greater than
MAX_INT, groups_search() function may look on the wrong side of the search
tree.
This solves some unfair "permission denied" problems.
