Subject: [PATCH iwl-net] i40e: Fix ST code value for Clause 45

ST code value for clause 45 that has been changed by
commit 8196b5fd6c73 ("i40e: Refactor I40E_MDIO_CLAUSE* macros")
is currently wrong.

The mentioned commit refactored ..MDIO_CLAUSE??_STCODE_MASK so
their value is the same for both clauses. The value is correct
for clause 22 but not for clause 45.

Fix the issue by adding a parameter to I40E_GLGEN_MSCA_STCODE_MASK
macro that specifies required value.

Fixes: 8196b5fd6c73 ("i40e: Refactor I40E_MDIO_CLAUSE* macros")
