scsi_transport_iscsi: return -EOVERFLOW for Too many iscsi targets

setting err as -EOVERFLOW for Too many iscsi targets.

Also fixes a spurious compiler warning for gcc 4.3.3 and gcc 4.4 :

  CC      drivers/scsi/scsi_transport_iscsi.o

drivers/scsi/scsi_transport_iscsi.c:678: warning: ‘err’ may be used uninitialized in this function
