scsi: ufs: ufshpb: Change sysfs node hpb_stats/rb_* prefix to start with rcmd_*
According to the documentation of the sysfs nodes rb_noti_cnt, rb_active_cnt and rb_inactive_cnt, these are all related to HPB recommendation in UPIU response packet. 'rcmd' (recommendation) should be the correct abbreviation. Change the sysfs documentation about these sysfs nodes to highlight what they mean under different HPB control modes.
