sunrpc: integer underflow in rsc_parse()
If we call groups_alloc() with invalid values then it's might lead to
memory corruption. For example, with a negative value then we might not
allocate enough for sizeof(struct group_info).
(We're doing this in the caller for consistency with other callers of
groups_alloc(). The other alternative might be to move the check out of
all the callers into groups_alloc().)
