[PATCH -tip][SCSI] scsi: scsi_transport_iscsi.c initialize thevariable before it get used

[Jaswinder Singh Rajput]

I am watching this problem from long time in -tip.

Subject: [PATCH] scsi: scsi_transport_iscsi.c initialize the variable before it get used

In some cases, err will be used uninitialized.

Also fixed compilation warning :

 CC      drivers/scsi/scsi_transport_iscsi.o
drivers/scsi/scsi_transport_iscsi.c: In function âiscsi_add_sessionâ:
drivers/scsi/scsi_transport_iscsi.c:678: warning: âerrâ may be used uninitialized in this function
