apparmor: change aad apparmor_audit_data macro to a fn macro
The aad macro can replace aad strings when it is not intended to. Switch to a fn macro so it is only applied when intended. Also at the same time cleanup audit_data initialization by putting common boiler plate behind a macro, and dropping the gfp_t parameter which will become useless.
