As we do when deleting ctrlr_channel, disconnect and then free I/O qpair in a ctrlr reset sequence. Deleting ctrlr_channel and resetting ctrlr_channel may cause conflicts. This patch processes such conflicts correctly. If destroy_ctrlr_channel_cb() is executed between pending and executing reset_destroy_qpair(), reset_destroy_qpair() is not executed because ctrlr_channel is not found. In this case, destroy_qpair_channel() starts disconnecting qpair and deletes ctrlr_channel. Then disconnected_qpair_cb() releases a reference to poll group. If destroy_ctrlr_channel_cb() is excuted between executing reset_destroy_qpair() and disconnected_qpair_cb(), destroy_ctrlr_channel_cb() skips ctrlr_channel for a reset sequence.
