ALSA: ac97: fix PM reference leak in ac97_bus_remove()

stable inclusion
from linux-4.19.198
commit 7c3a170279bf2cd870d30a97344e91db5dccf1d2

--------------------------------

[ Upstream commit a38e9330 ]

pm_runtime_get_sync will increment pm usage counter even it failed.
Forgetting to putting operation will result in reference leak here.
Fix it by replacing it with pm_runtime_resume_and_get to keep usage
counter balanced.
