cxgbe: fix setting wrong MTU

max_rx_pkt_len already includes ETHER_HDR_LEN and ETHER_CRC_LEN for the
mtu. But, the firmware also adds ETHER_HDR_LEN and ETHER_CRC_LEN to the
mtu specified. Fix by subtracting these values from the mtu before
passing it to firmware.

Fixes: 4b2eff452d2e ("cxgbe: enable jumbo frames")
