Subject: [PATCH 3.2 057/110] fuse: initialize fc->release before calling it

3.2.71-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Miklos Szeredi <mszeredi@...e.cz>

commit 0ad0b3255a08020eaf50e34ef0d6df5bdf5e09ed upstream.

fc->release is called from fuse_conn_put() which was used in the error
cleanup before fc->release was initialized.

[Jeremiah Mahler <jmmahler@...il.com>: assign fc->release after calling
fuse_conn_init(fc) instead of before.]

Signed-off-by: Miklos Szeredi <mszeredi@...e.cz>
Fixes: a325f9b92273 ("fuse: update fuse_conn_init() and separate out fuse_conn_kill()")
