btrfs-progs: don't use write_extent_to_disk() directly

Browse Source 
There are two call sites using write_extent_to_disk() directly:

- debug_corrupt_block() in btrfs-corrupt-block.c
- corrupt_keys() in btrfs-corrupt-block.c

The problem of write_extent_to_disk() is, it can only handle plain
profiles (All profiles except P/Q stripes of RAID56).

Calling it directly can corrupted RAID56 P/Q, and in the future we're
going to remove eb::fd/eb::dev_bytes, so remove such call sites with
write_and_map_eb().
