[PATCH] platform/x86: amd-pmc: Only report STB errors when STB enabled

[Mario Limonciello]

Currently if STB is disabled but an earlier function reported an
error an incorrect error will be emitted about failing to write to
STB.

Correct this logic error by only showing errors when STB is enabled.
