xfs: do not check NEEDSREPAIR if ro,norecovery mount.

Browse source 
If there is corrutpion on the filesystem andxfs_repair
fails to repair it. The last resort of getting the data
is to use norecovery,ro mount. But if the NEEDSREPAIR is
set the filesystem cannot be mounted. The flag must be
cleared out manually using xfs_db, to get access to what
left over of the corrupted fs.
