[PATCH 03/13] vfs: don't parse forbidden flags

[Miklos Szeredi]

Impossible to keep this blacklist properly synced with what mount(8) parses
and what it doesn't.  E.g. it has various forms of "*atime" options, but
not "atime"...

Other than being impossible to maintain, it also makes little sense.  So
just get rid of it.
