In host control mode, eviction is perceived as an extreme measure.
There are several conditions that both the entering and exiting regions
should meet, so that eviction will take place.

The common case however, is that those conditions are rarely met, so it
is normal that the act of eviction fails.  Therefore, Do not report an
error in host control mode if eviction fails.

Fixes: 6c59cb501b86 (scsi: ufs: ufshpb: Make eviction depend on region's reads)
