net/ice/base: fix tunnel type match word handling

Use a common function when selecting the proper word and mask match for
a tunnel type when programming switch rules.

Store switch recipe field mask as little endian, which avoids needing to
convert back to big endian after reading recipe from FW.

Obtain word mask from FW recipe.

Fix word matching element and index pairing.
