net/mlx5e: Properly enforce disallowing of partial field re-write offload

Currently we don't support partial header re-writes through TC pedit
action offloading. However, the code that enforces that wasn't err-ing
on cases where the first and last bits of the mask are set but there is
some zero bit between them, such as in the below example, fix that!

tc filter add dev enp1s0 protocol ip parent ffff: prio 10 flower
	ip_proto udp dst_port 2001 skip_sw
	action pedit munge ip src set 1.0.0.1 retain 0xff0000ff

Fixes: d79b6df6b10a ('net/mlx5e: Add parsing of TC pedit actions to HW format')
