tags: add safety check for len(record) while reading hgtagsfnodescache

I am trying to fix a breakage where somehow we end up getting a node of 12
length from `getfnode()`. Understanding the hgtagsfnodescache code, it seems
highly unlikely that it can happen unless one of `mctx.readfast().get()` or
`ctx.filenode()` is returning a node of 12 length.

For safety, I think it's better to add a check to make sure that record which we
are parsing is of same length we are expecting otherwise we consider that as
invalid record.
