Subject: [PATCH] main.c: revert check on console device

Fix kernel panic because of the missing /dev/console.

Revert Yocto-specific : "check console device file on fs when booting".

The initramfs used in this kernel needs to be of the smallest possible
size so we save a few kb by deploying an empty /dev which is populated
after boot by the init (kexecboot checks and recreates the devices
with or without devtmpfs).
