Subject: [PATCH] scsi: qla4xxx: turn qla4xxx_copy_from_fwddb_param() into void

This function always return '0' and no callers use the return value.
So make it a void function.

This eliminates the following coccicheck warning:
./drivers/scsi/qla4xxx/ql4_os.c:3642:5-7: Unneeded variable: "rc".
Return "0" on line 3741
