iwlwifi: mvm: Don't fail if PPAG isn't supported 

When we're copying the PPAG table into the cmd structure we're failing
if the table doesn't exist in ACPI or is invalid, or if the FW doesn't
support PPAG setting etc.

This is wrong because those are valid scenarios.  Fix this by not
failing in those cases.
