scsi: mpi3mr: Fix device loss during enclosure reboot due to zero link speed
During enclosure reboot or expander reset, firmware may report a link
speed of 0 in "Device Add" events while the link is still coming up.
The driver drops such devices, leaving them missing even after the link
recovers.
Fix this by treating link speed 0 as 1.5 Gbps during device addition so
the device is exposed to the OS. The actual link speed will be updated
later when link-up events arrive.
