Revert "smbd: fullpath based on fsp->fsp_name may contain an @GMT token"

This reverts commit e593c38f5a8602be497a29e145ccdd4f9cc595e7.

As stated in the original commit message, "When canonicalize_snapshot_path()
starts actually stripping off @GMT tokens, we can remove this again."

canonicalize_snapshot_path() now strips off @GMT tokens from
any SMB1 names, so this is now not needed anymore.
