Christian Brauner b0fa673c8c fs: add file and path permissions helpers ...

[ Upstream commit 02f92b3868a1b34ab98464e76b0e4e060474ba10 ]

Add two simple helpers to check permissions on a file and path
respectively and convert over some callers. It simplifies quite a few
codepaths and also reduces the churn in later patches quite a bit.
Christoph also correctly points out that this makes codepaths (e.g.
ioctls) way easier to follow that would otherwise have to do more
complex argument passing than necessary.
