ixgbe: Fix cls_u32 offload support for L4 ports

Fix support for 16 bit source/dest port matches in ixgbe model.
u32 uses a single 32-bit key value for both source and destination ports
starting at offset 0. So replace the 2 functions with a single function
that takes this key value/mask to program both source and dest ports.

Verified with the following filter:

 #tc qdisc add dev p4p1 ingress
 #tc filter add dev p4p1 parent ffff: protocol ip prio 99 \
	handle 1: u32 divisor 1
 #tc filter add dev p4p1 parent ffff: protocol ip prio 99 \
	handle 800:0:10 u32 ht 800: link 1: \
	offset at 0 mask 0f00 shift 6 plus 0 eat match ip protocol 6 ff
 #tc filter add dev p4p1 parent ffff: protocol ip prio 99 \
	handle 1:0:10 u32 ht 1: \
	match tcp src 1024 ffff match tcp dst 80 ffff action drop
 #tc filter add dev p4p1 parent ffff: protocol ip prio 99 \
	handle 1:0:11 u32 ht 1: \
	match tcp src 1025 ffff action drop
 #tc filter add dev p4p1 parent ffff: protocol ip prio 99 \
	handle 1:0:12 u32 ht 1: \
	match tcp dst 81 ffff action drop
