remoteproc: k3-r5: Fix error handling when power-up failed

Browse Source 
commit 9ab27eb586 upstream.

By simply bailing out, the driver was violating its rule and internal
assumptions that either both or no rproc should be initialized. E.g.,
this could cause the first core to be available but not the second one,
leading to crashes on its shutdown later on while trying to dereference
that second instance.

Fixes: 61f6f68447 ("remoteproc: k3-r5: Wait for core0 power-up before powering up core1")
