apparmor: use kvfree_sensitive to free data->data
commit 2bc73505a5cd2a18a7a542022722f136c19e3b87 upstream.
Inside unpack_profile() data->data is allocated using kvmemdup() so it
should be freed with the corresponding kvfree_sensitive().
Also add missing data->data release for rhashtable insertion failure path
in unpack_profile().
Found by Linux Verification Center (linuxtesting.org).
