btrfs: scrub: limit RST scrub to chunk boundary
[BUG]
If there is an extent beyond chunk boundary, currently RST scrub would
error out.
[CAUSE]
In scrub_submit_extent_sector_read(), we completely rely on
extent_sector_bitmap, which is populated using extent tree.
The extent tree can be corrupted that there is an extent item beyond a
chunk.
In that case, RST scrub would fail and error out.
[FIX]
Despite the extent_sector_bitmap usage, also limit the read to chunk
boundary.
