cifs: reinstate original behavior again for forceuid/forcegid
forceuid/forcegid should be enabled by default when uid=/gid= options are
specified, but commit 24e0a1eff9e2 ("cifs: switch to new mount api")
changed the behavior. Due to the change, a mounted share does not show
intentional uid/gid for files and directories even though uid=/gid=
options are specified since forceuid/forcegid are not enabled.
This patch reinstates original behavior that overrides uid/gid with
specified uid/gid by the options.
Fixes: 24e0a1eff9e2 ("cifs: switch to new mount api")
