USB: cdc-acm: fix runtime PM imbalance at shutdown
commit 5292afa657d0e790b7479ad8eef9450c1e040b3d upstream.
Make sure only to decrement the PM counters if they were actually
incremented.
Note that the USB PM counter, but not necessarily the driver core PM
counter, is reset when the interface is unbound.
Fixes: 11ea859d64b6 ("USB: additional power savings for cdc-acm devices
that support remote wakeup")
