V4L/DVB (6275): V4L: vivi.c remove the "resource" locking
The "resource" locking in vivi isn't needed since
streamon/streamoff/read_stream do mutual exclusion using
q->reading/q->streaming.
Plus it is sort of broken:
a) res_locked() use in vivi_read() is racey.
b) res_free() calls mutex_lock twice causing streamoff to break
