fuse: revalidate group id cache on uid/gid change detection
- Remember the uid and gid of the pid at the time of caching the group id list. - Next time when referring to the cache confirm that uid and gid of that pid has not changed since. If it has, treat it like a timeout/cache miss. - Solves group id caching issue caused when Samba runs on gluster FUSE mount and changes the uid/gid on a per syscall basis.
