soc: qcom: pil: Fix error case scenario in subsystem ramdump

During ramdump collection we assign memory to HLOS from subsystem for
non-secure pil. Whether ramdump collection is successful or not, we
should assign memory back to subsystem. This is to avoid access
violations in powerup path which happens after ramdump.
