staging: vt6656: rxtx.c [BUG] s_vGetFreeContext dead lock on null apTD.
There seems to be race condition that the device is ndo_start_xmit
at a point where the device is closing and apTD is NULL resulting
in dead lock.
Add a NULL check to apTD and return NULL to calling functions.
This is more likely on 64 bit systems.
