apparmor: allocate xmatch for nullpdb inside aa_alloc_null

Browse Source 
attach->xmatch was not set when allocating a null profile, which is used in
complain mode to allocate a learning profile. This was causing downstream
failures in find_attach, which expected a valid xmatch but did not find
one under a certain sequence of profile transitions in complain mode.

This patch ensures the xmatch is set up properly for null profiles.
