app/test: avoid freeing mbufs twice in qat test

Test_multi_session was freeing mbufs used in the multiple sessions
created and setting obuf to NULL after it, but ibuf was not being
set to NULL, and therefore, it was being freed again (ibuf and obuf
are pointing at the same address), in the ut_teardown() function.
