scsi: ufs: core: Fix the return value documentation

Browse source

ufshcd_wait_for_dev_cmd() and all its callers can return an OCS error.
OCS errors are represented by positive integers. Remove the WARN_ONCE()
statements that complain about positive error codes and update the
documentation.

Keep the behavior of ufshcd_wait_for_dev_cmd() because this return value
may end be passed as the second argument of bsg_job_done() and
bsg_job_done() handles positive and negative error codes differently.
