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.

Fixes: c263b4ef737e ("scsi: ufs: core: mcq: Configure resource regions")
