cmd: ide: Make the first device the default one

lbmeng · trini · commit 584f316f115d · 2017-09-10T12:27:43.000-04:00
At present the IDE device number is initialized to -1, which means
we cannot type "ide read" command before setting the device number
via "ide device #".

For convenience, let's set the first device as the default one.
