As Qu mentioned in this thread
(https://www.spinics.net/lists/linux-btrfs/msg64469.html), compression
can cause regular extent to co-exist with inlined extent. This coexistence
makes things confusing. Since it was permitted currently, so fix
btrfsck to prevent a bunch of error logs that will make user feel
panic.
When check file extent, record the extent_end of regular extent to check
if there is a gap between the regular extents. Normally there is only one
inlined extent, so the extent_end of inlined extent is useless. However,
if regular extent can co-exist with inlined extent, the extent_end of
inlined extent also need to record.
