51d5712982 modules/mqnic: Introduce proper error path on failing to allocate RX buffers 
This basically allows the "refilling" of RX buffers to fail. A fail to allocate
RX buffers can occur on bringing a network device up or when changing the number
of RX channels at run-time through `ethtool -L <ndev> rx <num>`.
