Xiu Jianfeng bf7ebebce2 apparmor: Fix memleak in aa_simple_write_to_buffer() ...

commit 417ea9fe97 upstream.

When copy_from_user failed, the memory is freed by kvfree. however the
management struct and data blob are allocated independently, so only
kvfree(data) cause a memleak issue here. Use aa_put_loaddata(data) to
fix this issue.

Fixes: a6a52579e5 ("apparmor: split load data into management struct and data blob")
