btrfs: fix the length of reserved qgroup to free
commit 2b084d8205949dd804e279df8e68531da78be1e8 upstream.
The dealloc flag may be cleared and the extent won't reach the disk in
cow_file_range when errors path. The reserved qgroup space is freed in
commit 30479f31d44d ("btrfs: fix qgroup reserve leaks in
cow_file_range"). However, the length of untouched region to free needs
to be adjusted with the correct remaining region size.
Fixes: 30479f31d44d ("btrfs: fix qgroup reserve leaks in cow_file_range")
