sstables: Remove host id mismatch warning for sstable streaming

Tablet migration transfers sstable files without changing origin
host-id.  As it should, becuase those sstables were not written on the
destination host, and should be ignored by commit log replay.

So it's a normal situation, and it's confusing to see this warning in
logs.

Fixes #26957
