If the request is queued and is not in completing, we can abort
it safely.
If the state of the request is NEED_BUFFERING, the request is
queued to both tqpair->group->group.pending_buf_queue and
the queue per state.
If the state is AWAITING_R2T_ACK, the request is queued to the
queue per state.
Dequeueing from the queue per state is done in
nvmf_tcp_req_set_state(). Hence explicit dequeuing only when the
state of the request is NEED_BUFFERING.
Most abort operation is common between two cases. We can use fallthrough
in switch-case but factor out the common operation into a helper
function nvmf_tcp_req_set_abort_status() instead because we may use
the helper function in future and using helper function is easier to
read than fallthrough.
