virtio_fs: introduce virtio_fs_put_locked helper
Introduce a new helper function virtio_fs_put_locked to encapsulate the
common pattern of releasing a virtio_fs reference while holding a lock.
The existing virtio_fs_put helper will be used to release a virtio_fs
reference while not holding a lock.
Also add an assertion in case the lock is not taken when it should.
