Subject: iommu/fsl_pamu: Fix resource leak in fsl_pamu_probe()
Git-commit: 73f5fc5f884ad0c5f7d57f66303af64f9f002526
Patch-mainline: v6.2-rc1
References: git-fixes

The fsl_pamu_probe() returns directly when create_csd() failed, leaving
irq and memories unreleased.
Fix by jumping to error if create_csd() returns error.

Fixes: 695093e38c3e ("iommu/fsl: Freescale PAMU driver and iommu implementation.")
