btrfs: fix raid56 scrub failed in xfstests btrfs/072
The xfstests btrfs/072 reports uncorrectable read errors in dmesg,
because scrub forgets to use commit_root for parity scrub routine
and scrub attempts to scrub those extents items whose contents are
not fully on disk.
To fix it, we just add the @search_commit_root flag back.
