ice: Fix FV offset searching

Checking only protocol ids while searching for correct FVs can lead to a
situation, when incorrect FV will be added to the list. Incorrect means
that FV has correct protocol id but incorrect offset.

Call ice_get_sw_fv_list with ice_prot_lkup_ext struct which contains all
protocol ids with offsets.

With this modification allocating and collecting protocol ids list is
not longer needed.
