PCI: Increment PM usage counter when probing reset methods
We can get different results probing reset methods for a device depending
on its power state. For example, reading the PM control register of a
device in D3cold will always indicate NoSoftRst+ because we get ~0 data
when the config read fails on PCI, preventing us from correctly probing PM
reset support.
Increment the PM usage counter before any probes and use the cleanup __free
facility to automatically drop the usage counter out of scope.
