For read_data_extent() in convert/main.c it's using mirror number in a
incorrect way, which will not get correct copy for RAID1:
for (cur_mirror = 0; cur_mirror < num_copies; cur_mirror++) {
In such case, for RAID1 @cur_mirror will only be 0 and 1.
However for 0 and 1 case, btrfs_map_block() will only return the first
copy. To reach the 2nd copy, it correct @cur_mirror range should be 1
and 2.
So with this off-by-one error, btrfs-image will never be able to read
out data extent if the first stripe of the chunk is the missing one.
Fix it by starting @cur_mirror from 1 and to @num_copies (including).
