net/netvsc: avoid possible live lock

Since the ring buffer with host is shared for both transmit
completions and receive packets, it is possible that transmitter
could get starved if receive ring gets full.

Better to process all outstanding events which frees up transmit
buffer slots, even if means dropping some packets.

Fixes: 7e6c82430702 ("net/netvsc: avoid over filling Rx descriptor ring")
