From: Filipe Manana <fdmanana@xxxxxxxx>
We exercise corrupting an inline extent and inline extents can't be created
with nodatacow, we get instead a regular file extent item and if we attempt
to corrupt its disk_bytenr field with btrfs-corrupt-block we fail tree-checker
validation at mount time resulting in failure to mount and the following in
dmesg:
[514127.759739] BTRFS critical (device sdc): corrupt leaf: root=5 \
block=30408704 slot=8 ino=257 file_offset=0, invalid disk_bytenr for \
file extent, have 7416089308958521981, should be aligned to 4096
[514127.762715] BTRFS error (device sdc): read time tree block corruption \
detected on logical 30408704 mirror 1
So add a _require_btrfs_no_nodatacow call to the test.
