aa_mk_null_file is using simple_pin_fs/simple_release_fs with local
variables as arguments, for what would amount to a simple
vfs_kern_mount/mntput pair if everything was inlined. Just use
the normal filesystem API since the reference counting is not needed
here (it is a local variable and always 0 on entry and on exit).
There is no functional change intended.
