fuse: add missing FR_FORCE
commit 2e38bea99a80eab408adee27f873a188d57b76cb upstream.
fuse_file_put() was missing the "force" flag for the RELEASE request when
sending synchronously (fuseblk).
If this flag is not set, then a sync request may be interrupted before it
is dequeued by the userspace filesystem. In this case the OPEN won't be
balanced with a RELEASE.
[js] force is a variable, not a bit
