net/mlx5: fix header reformat action hash key

Currently, header reformat action uses the hash list 32-bit key
generated in header reformat register function directly. The key will
not be recalculated in the hash list function.

As the 64-bit key is composed of the 32-bit attributes and 32-bit
reformat buffer csum, the hash list function only gets 32-bit key
directly will take the attribute part only, csum part will be ignored.
For different header reformat actions, the attributes can be the same,
while the buffer will be different. Only take the attribute part causes
lots of the conflicts.

This commits adds the attribute part and the significant different csum
part for the key.
