fuse: fix memleak in cuse_channel_open
[ Upstream commit 9ad09b1976c562061636ff1e01bfc3a57aebe56b ]
If cuse_send_init fails, need to fuse_conn_put cc->fc.
cuse_channel_open->fuse_conn_init->refcount_set(&fc->count, 1)
->fuse_dev_alloc->fuse_conn_get
->fuse_dev_free->fuse_conn_put
Fixes: cc080e9e9be1 ("fuse: introduce per-instance fuse_dev structure")
