[PATCH 7/8] xfs_repair: don't create block maps for data files

Repair only queries inode block maps for inode forks that map filesystem
metadata. IOWs, it only uses it for directories, quota files, symlinks,
and extended attributes. It doesn't use it for regular files or
realtime files, so exclude its use for these files to reduce processing
times for heavily fragmented regular files.
