Subject: [PATCH] scsi: snic: make snic_io_exch_ver_cmpl_handler() void

This function do not need a return value and no users use it's return
value. So we can make it void.

This also fixes the coccicheck warning:

drivers/scsi/snic/snic_ctl.c:163:5-8: Unneeded variable: "ret". Return
"0" on line 228
