xfs: streamline the directory iteration code for scrub
Currently, online scrub reuses the xfs_readdir code to walk every entry
in a directory. This isn't awesome for performance, since we end up
cycling the directory ILOCK needlessly and coding around the particular
quirks of the VFS dir_context interface.
Create a streamlined version of readdir that keeps the ILOCK (since the
walk function isn't going to copy stuff to userspace), skips a whole lot
of directory walk cursor checks (since we start at 0 and walk to the
end) and has a sane way to return error codes.
Note: Porting the dotdot checking code is left for a subsequent patch.
