qla4x: fix ql4_mbx tcp_source_port_num

From: Randy Dunlap <[email protected]>

Fix sparse warning, which indicates a precedence problem and the data value always being 0:

drivers/scsi/qla4xxx/ql4_mbx.c:470:66: warning: right shift by bigger than source value

Sorry if you already received this patch; I thought that I had already sent it, but I can't find it anywhere.

And how about a MAINTAINERS entry for qla4xxx, please?
