scsi: ufs: core: Enable link lost interrupt

commit 6d17a112e9a63ff6a5edffd1676b99e0ffbcd269 upstream.

Link lost is treated as fatal error with commit c99b9b230149 ("scsi: ufs:
Treat link loss as fatal error"), but the event isn't registered as
interrupt source. Enable it.

Hi Jason,

Something must have gone wrong during the bisection process. Commit
8d5c106fe216 ("scsi: ufs: core: Enable link lost interrupt") only affects the UFS driver and hence cannot change the behavior of a SAS controller. How about repeating the bisection process?

Thanks,

Bart.
