Instead of tracking which tags are in use in the ufs_hba.lrb_in_use bitmask, rely on the block layer tag allocation mechanism. This patch removes the following busy-waiting loop if ufshcd_issue_devman_upiu_cmd() and the block layer accidentally allocate the same tag for a SCSI request: * ufshcd_queuecommand() returns SCSI_MLQUEUE_HOST_BUSY. * The SCSI core requeues the SCSI command.
