The existing code does not allow the MTU to be set to the maximum even
after an XDP program supporting multiple buffers is attached. Fix it
to set the netdev->max_mtu to the maximum value if the attached XDP
program supports mutiple buffers, regardless of the current MTU value.
Also use a local variable dev instead of repeatedly using bp->dev.
Fixes: 1dc4c557bf ("bnxt: adding bnxt_xdp_build_skb to build skb from multibuffer xdp_buff")
