Subject: fuse: add missing FR_FORCE

From: Miklos Szeredi <[email protected]>

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.
