qcacmn: assert on processing invalid RX ring descriptors

Browse Source 
Currently, we break the dp_rx_process() reap loop when we encounter
a ring descriptor with invalid bit set in SW cookie. If the HW
has copied old/stale entries in the ring, then we will end up
processing the same entry every time we try to reap the ring.
Instead, assert on processing such invalid entries so that
we can obtain useful debug information.
