ANDROID: scsi: ufs: Fix locking in ufshcd_queuecommand()

Browse Source 
Commit 0fd420005c ("Merge 5.15.89 into android14-5.15") added an
rcu_read_lock() call in ufshcd_queuecommand() that is not present in the
upstream kernel. Since this makes locking in ufshcd_queuecommand()
unbalanced, remove that rcu_read_lock() call again.
