[PATCH 1/2] fs/stat.c: drop the last new_valid_dev check

From: Yaowei Bai
Date: Fri Nov 13 2015 - 22:06:31 EST

New_valid_dev() always returns true, so that's unnecessary to perform
new_valid_dev() checks in some filesystems. Most checks of new_valid_dev()
have been removed so let's drop this last one and then we can remove
new_valid_dev() from the source code.

No functional change.
