fuse: add feature flag for expire-only
Add an init flag idicating whether the FUSE_EXPIRE_ONLY flag of
FUSE_NOTIFY_INVAL_ENTRY is effective.
This is needed for backports of this feature, otherwise the server could
just check the protocol version.
Fixes: 4f8d37020e1f ("fuse: add "expire only" mode to FUSE_NOTIFY_INVAL_ENTRY")
Cc: <stable@vger.kernel.org> # v6.2
