[PATCH] proc: register filesystem last

From: Alexey Dobriyan
Date: Fri Mar 09 2018 - 17:27:18 EST


As soon as register_filesystem() exits, filesystem can be mounted.
It is better to present fully operational /proc.

Of course it doesn't matter because /proc is not modular
but do it anyway.

Drop error check, it should be handled by panicking.
