[SCSI] mptfusion: Corrected declaration of device_missing_delay
device missing delay is 8 bit value in io unit pg1. Making correct variable declaration for device_missing_delay. The driver is storing the calculated device missing delay in IOC structure as a u8 instead of a u16. It needs to be a u16 if the delay is > 255.
