[stgt] Segfault with 2 initiators connecting to 1 target

[Ty Christensen]

> I'm running CentOS 6.3 and the packaged tgtd version 1.0.24 to share out a single target to multiple initiators.  The initiators all use the target as a boot volume, and they're running Windows Embedded with the EWF filter driver filtering out the writes to the volume.  My initiator names are specified by iPXE, and I'm only using the iPXE default so each machine name announces itself uniquely to the target.  I can boot, run, and shutdown a single initiator normally without trouble.
