vfs: Convert efivarfs to use the new mount API

Convert the efivarfs filesystem to the new internal mount API as the old
one will be obsoleted and removed.  This allows greater flexibility in
communication of mount parameters between userspace, the VFS and the
filesystem.

[AV: get rid of efivarfs_sb nonsense - it has never been used]

See Documentation/filesystems/mount_api.txt for more information.
