fs/super.c: stop calling fscrypt_destroy_keyring() from __put_super()

Browse source 
Now that the key associated with the "test_dummy_operation" mount option
is added on-demand when it's needed, rather than immediately when the
filesystem is mounted, fscrypt_destroy_keyring() no longer needs to be
called from __put_super() to avoid a memory leak on mount failure.

Remove this call, which was causing confusion because it appeared to be
a sleep-in-atomic bug (though it wasn't, for a somewhat-subtle reason).
