This code calculates the difference between two pointers and then stores
it in an off_t, which is intended for file offsets.
In this particular case, the offset will never be large enough to
overflow off_t, but use the correct ptrdiff_t type anyway.

We already require the assert header from the C standard library,
so use that instead of RTE_VERIFY to further isolate DPDK
dependencies.

We need to return -1, when there is still tasks. From the
usage, return 1 is wrong.

SPDK_NOTICELOG() can already do printf()-style formatting, so there is
no need to use snprintf() on a temporary buffer first.

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.

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.

that must execute on the polling thread before the poller starts execution

commit 5d8c94536a7d1d4c1f0ee3349188bf0e7e8c9e74; add a field to
spdk_iscsi_conn to track the lcore so this can be re-added.

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.
