bnx: Disable RX max BDs based interrupt moderation

The RX max coalesce BDs is limited to 255, which means that the chip will
generate ~5800 interrupts/s when it sinks 1.48Mpps tiny packets.  However,
interrupt rate at 4000Hz is already enough for the chip to sink 1.48Mpps
tiny packets, so ticks based RX interrupt moderation should be prefered.
