btrfs: zoned: use zone aware sb location for scrub
commit 74098a989b9c3370f768140b7783a7aaec2759b3 upstream.
At the moment scrub_supers() doesn't grab the super block's location via
the zoned device aware btrfs_sb_log_location() but via btrfs_sb_offset().
This leads to checksum errors on 'scrub' as we're not accessing the
correct location of the super block.
So use btrfs_sb_log_location() for getting the super blocks location on
scrub.
