Subject: dpif-linux: Avoid logging error on ENOENT in dpif_linux_is_internal_device().
X-Git-Tag: v1.1.1~44

dpif-linux: Avoid logging error on ENOENT in dpif_linux_is_internal_device().

ENOENT can be returned if the kernel module isn't loaded.  If that's the
case then we've already logged that and there's no point in logging it
again.
