net/mlx5e: RX, Test the XDP program existence out of the handler

Browse source

Instead of early return inside mlx5e_xdp_handle(), let the caller check
if an XDP program is loaded.  This allows saving a few unnecessary
function calls and calculations in case !prog.

Performance test: single core, drop packets in iptables
Before: 3,872,504 pps
After:  3,975,628 pps (+2.66%)
