Subject: [PATCH] power: reset: nvmem-reboot-mode: quiet some device deferrals

Some errors are being logged that are really due to deferrals,
which is confusing to users. Use dev_err_probe() to handle when to log
at error level versus debug. This also has the added bonuses of logging
to devices_deferred and printing the error value.
