Patch for v4l2src to put back replaced buffer...and fix race condition...

Through extended 24 hour testing, I found a race condition between dqbuf and
qbuf functions that can undermine replacement of original buffer in the qbuf
function.  This warranted the introduction of mutex protection in both the
aforementioned functions.
