net/ice/base: add profile validation on switch filter

[ upstream commit a62f095 ]

Profile type was determined without validation when getting
switch field vector bitmap. It caused error when associating
profile id with given recipe if no lookup elements were given.
Add profile validation to check if the profile is existing
before getting bitmap.

Fixes: 5574422 ("net/ice/base: associate recipes by profile type")
