VFS: add vfs_lookup_open() for nfsd

Browse source

vfs_lookup_open() is a limited version of lookup_open() which is
exported for nfsd to use - to replace dentry_create().

It is limited in that no filename is given (thus no auditing) and no
LOOKUP_ flags are passed.  A few "intent" LOOKUP flags are deduced from
the open flags.

If a non-regular file is found and appropriate error is returned and no
file is opened.
