target_del() calls handle_iscsi_events() which may recursively call target_del().

We found this bug when we add ZFS zvol to vdisk_blockio, remove it from copy
manager, and change ALUA state. After that the zvol would be in constant busy
state, even if we remove all scst modules.
The problem is that blockio_on_alua_state_change_finish will unconditionally
vdisk_open_fd. But for the above mentioned case, tgt_dev_cnt will be zero, so
the fd is permanently leaked. We fix this by only do vdisk_open_fd when
tgt_dev_cnt is not zero.

isert: fix double free of a fake request
A nop that is sent from the scst is treated as a fake request.
When a fake request is allocated we release it immediately,
so it's wrong to release it also on a completion error (isert_pdu_err).
This commit fix a NULL dereference bug when receiving completion with
error on this nop.

It is possible to get ESTABLISHED RDMACM event while the connection

At teardown the refcount is reduced to zero and we start releasing the
