net: alacritech: Partially revert "net: alacritech: Switch to use dev_err_probe()"

This reverts commit bf4d87f884fe8a4b6b61fe4d0e05f293d08df61c because it
introduced dev_err_probe() in non-probe path, which is not desired.

In general, calling dev_err_probe() after successful probe in case of
handling -EPROBE_DEFER error, will set deferred status on the device
already probed. This is however not a problem here now, because
dev_err_probe() in affected places is used for handling errors from
request_firmware(), which does not return -EPROBE_DEFER. Still usage of
dev_err_probe() in such case is not correct, because request_firmware()
could once return -EPROBE_DEFER.
