[ Upstream commit 1e2517d126171a41f801738ffd19687836cd178a ]
Commit d5269c4553a6 ("remoteproc: qcom: q6v5: Propagate EPROBE_DEFER")
fixed up our probe code to handle -EPROBE_DEFER, but it ignored one of
our interrupts, and it also didn't really handle all the other error
codes you might get (e.g., with a bad DT definition). Handle those all
explicitly.
