bnx2x: fix panic when TX ring is full
There is a off by one error in the minimal number of BD in
bnx2x_start_xmit() and bnx2x_tx_int() before stopping/resuming tx queue.
A full size GSO packet, with data included in skb->head really needs
(MAX_SKB_FRAGS + 4) BDs, because of bnx2x_tx_split()
This error triggers if BQL is disabled and heavy TCP transmit traffic
occurs.
bnx2x_tx_split() definitely can be called, remove a wrong comment.
