firmware: arm_scmi: Make Rx chan_setup fail on memory errors

[ Upstream commit be9ba1f7 ]

SCMI Rx channels are optional and they can fail to be setup when not
present but anyway channels setup routines must bail-out on memory errors.

Make channels setup, and related probing, fail when memory errors are
reported on Rx channels.
