An application may submit all-zeros masks for a given field
to be used in two given specifications and, in the meantime,
use different unmasked values. Later on, when compared, the
two specifications will prove unequal, and, if the rules in
question are outer, the client driver will have to allocate
a separate rule for the second specification. Provided that
all other match criteria are the same, the HW will deem the
two outer rules being duplicates, which is in fact the case.
Apply masks to values in efx_mae_match_spec_field_set() API
to fix the issue and avoid duplicate outer rule allocations.
