iser-target: Fix multi network portal shutdown regression

This patch fixes a iser-target specific regression introduced in
v3.15-rc6 with:

commit 14f4b54fe38f3a8f8392a50b951c8aa43b63687a
Author: Sagi Grimberg <sagig@mellanox.com>

    Target/iscsi,iser: Avoid accepting transport connections during stop stage

where the change to set iscsi_np->enabled = false within
iscsit_clear_tpg_np_login_thread() meant that a iscsi_np with
two iscsi_tpg_np exports would have it's parent iscsi_np set
to a disabled state, even if other iscsi_tpg_np exports still
existed.

This patch changes iscsit_clear_tpg_np_login_thread() to only
set iscsi_np->enabled = false when shutdown = true, and also
changes iscsit_del_np() to set iscsi_np->enabled = true when
iscsi_np->np_exports is non zero.
