Can Guo 0666c173a0 scsi: ufs: ufs-qcom: Fix race conditions caused by ufs_qcom_testbus_config()
[ Upstream commit 89dd87acd4 ]

If ufs_qcom_dump_dbg_regs() calls ufs_qcom_testbus_config() from
ufshcd_suspend/resume and/or clk gate/ungate context, pm_runtime_get_sync()
and ufshcd_hold() will cause a race condition. Fix this by removing the
unnecessary calls of pm_runtime_get_sync() and ufshcd_hold().
