Shuhei Matsumoto 703a5473f7 iscsi: Restore the previous bug fix for LUN hot plug
One recent commit destroyed the critical bug fix for LUN hot plug.
Hence this patch restores the critical bug fix. Simple revert is
not possible because connections are assigned to poll groups
instead of cores now. But we can revert easily because earlier
version of the recent patch did that.

Fixes #925

The github issue was caused by commit 8cf1945432f383ce8906f000d3296d1584573234.
The bug fix restored by this patch is commit 1f6a78620d1f4b7470ccf5ff378fd2eb6cf49c5f.
The reference we can follow to create this patch is earlier version
of commit fb641c4b542ec7616eeb6b88cce1e14069e66d62.
