session: fix tx_fifo clear and incorrect bitmap invalidation
The tx_fifo of session may not be set up yet, if app request to
disconnect the session, svm_fifo_dequeue_drop_all will crash.
In debug image, ho_session_alloc will do clib_bitmap_validate to
prevent race condition, however the input is not correct which
will make vpp crash.
Type: fix
