scsi: ufs: mcq: qcom: Clean the return path of ufs_qcom_mcq_config_resource()

Smatch static checker reported:
drivers/ufs/host/ufs-qcom.c:1469
ufs_qcom_mcq_config_resource() info: returning a literal zero is
cleaner

Fix the above warning by returning in place instead of a jump to a label.
Also remove the usage of devm_kfree() as it's unnecessary in this function.
