netdev-provider: fix comments for netdev_rxq_recv

Browse Source 
Commit 64839cf43 applies batch objects to netdev-providers, but
some comments were not updated accordingly. Fix these:
   - replace 'pkts' with 'batch'
   - replace '*cnt' with 'batch->count'
   - replace MAX_RX_BATCH with NETDEV_MAX_BURST
   - remove superfluous whitespace
