platform/x86/amd: pmc: Dump idle mask during "check" stage instead

The idle mask is dumped during the "prepare" and "restore" stage
right now, which helps to demonstrate issues only related to the
first s2idle entry.

If the system has entered s2idle once, but was woken up never
breaking the s2idle loop but also never went back to sleep we
might still have another issue to deal with however.

Move the dynamic debugging message here so that we'll catch it on
each iteration.
