commit f484a794
category: bugfix
bugzilla: 188443, https://gitee.com/openeuler/kernel/issues/I6I8YD
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f484a794e4ee2a9ce61f52a78e810ac45f3fe3b3

----------------------------------------

If during iscsi_sw_tcp_session_create() iscsi_tcp_r2tpool_alloc() fails,
userspace could be accessing the host's ipaddress attr. If we then free the
session via iscsi_session_teardown() while userspace is still accessing the
session we will hit a use after free bug.

Set the tcp_sw_host->session after we have completed session creation and
can no longer fail.
