MdeModulePkg/ScsiDisk: Increase the value of SCSI_DISK_TIMEOUT to 30s 

As ScsiDisk and ScsiBus driver are used to manage SCSI or ATAPI devices,
the timeout value is updated to 30s to follow ATA/ATAPI spec in which
the device may take up to 30s to respond command.

The change is used to solve device compatibility issue found with a TEAC
DV-W28S-WZ3 slim DVD plus a SONY AccuCORE DVD-R media in which the DVD
spends 8s to response READ_CAPACITY cmd after resetting the host machine.
