PCI: tegra: Fix runtime PM imbalance in pex_ep_event_pex_rst_deassert()

stable inclusion
from stable-5.10.39
commit 4800a98bcfe472a5cde5ac51830884d707a46fcc
bugzilla: 51881
CVE: NA

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

[ Upstream commit 5859c926 ]

pm_runtime_get_sync() will increase the runtime PM counter
even it returns an error. Thus a pairing decrement is needed
to prevent refcount leak. Fix this by replacing this API with
pm_runtime_resume_and_get(), which will not change the runtime
PM counter on error.
