tags-fnode-cache: do not repeatedly open the filelog in a loop

While getting multiple hgtagsfnodecache entries, we were opening (and closing)
the `.hgtags` filelog for each iteration. The meant repeatedly reading and
parsing the version same information from disk. A quite costly operation.

We no longer do this, leading to a sizable improvement in `hg debugupdatecache`
run for an already warm repositories.
