[PATCH] target: make sure the np under each tpg is unique

[mingzhe.zou@easystack.cn]

From: ZouMingzhe <mingzhe.zou@easystack.cn>

iscsit_tpg_check_network_portal() has two-layer for loop, and
should return true When a match is found. Then, the tpg loop
will still continue after break the tpg_np loop. If this tpg_np
is not the last, the match value will be changed.

This patch break all loops after finding a match, and make sure
the np under each tpg is unique.
