Fix an error case in ufs_qcom_mcq_config_resource(), where the
return value is set to 0 before passing it to PTR_ERR.
This led to Smatch warning:
drivers/ufs/host/ufs-qcom.c:1455 ufs_qcom_mcq_config_resource() warn:
passing zero to 'PTR_ERR'
Fixes: c263b4ef737e ("scsi: ufs: core: mcq: Configure resource regions")
