scsi: hisi_sas: Change DMA setup lock timeout to 2.5s
DMA setup lock timeout protection is added when DMA setup frames are
received. It's a function outside the protocol and used to prevent SATA
disk I/Os from being delivered for a long time. The default value is 100ms,
it's too strict and easily triggered timeout when the disk is overloaded or
faulty. Based on the average I/O latency of 300 disks, we adjust the value
to 2.5s.
