net&iscsi: force overwrite "*" and "[*]" by wildcard

Browse Source 
SPDK have used "*" and "[*]" as wildcard address
for iSCSI network portal. These abbreviations may be convenient
but unusual. If "*" or "[*]" is used, output warning message
and forcefully overwrite "*" or "[*]" by "0.0.0.0" or "[::]"
respectively.

After confirming that the usage of "*" and "[*]" is not used any
more, the code for "*" and "[*]" will be deleted.
