[SCSI] mvsas: increase port type detection delay to suit Seagate's 10k6 drive ST3450856SS 0003 

I increased the delay step by step until loading of mvsas
reliably detected the drive 200 times in sequence. A much better
approach would be to monitor the hardware for some flag which
indicates that port detection has finished, but I do not have any
hardware documentation.
