Fixes gcc '-Wunused-but-set-variable' warning:

fs/fuse/virtio_fs.c: In function virtio_fs_wake_pending_and_unlock:
fs/fuse/virtio_fs.c:983:20: warning: variable fc set but not used [-Wunused-but-set-variable]

It is not used since commit 7ee1e2e631db ("virtiofs:
No need to check fpq->connected state")
