ff38547d80 iSCSI: change return value of spdk_iscsi_conn_free_tasks
We need to return -1, when there is still tasks. From the
usage, return 1 is wrong.

2e9cd2cd77 iscsi: eliminate pointless temporary log buffer
SPDK_NOTICELOG() can already do printf()-style formatting, so there is
no need to use snprintf() on a temporary buffer first.

dfe5d83743 iscsi: ensure we have a conn->sess before trying to stop a poller
There are some error paths that can get to spdk_iscsi_conn_stop_poller()
before the conn's session is set.  So check whether the session is NULL
before trying to check its session type.

f167fac386 iscsi: start all sessions for a target node on the same lcore
This ensures against races, when an existing session to a target node
stalls, causing the initiator to create a new session.  These new
session's connection may get migrated to a different core than the
core of the stalled session.

In practice, this does not happen, but is a common occurrence when
debugging the iSCSI target using gdb.

5d8c94536a event: hide struct spdk_poller internals
This leaves more flexibility for future changes to the poller
representation without requiring API changes (after this one).

It also prevents the user from accidentally using poller fields in a
non-thread-safe way, since they can't be accessed directly anymore.
