This patch marks device as failed for the write/flush errors
so that it can be brought out of the RW device list. However
if the chunk render is incomplete due to missing of a device
then the volume/raid fails, so this situation is handled by
calling btrfs_handle_fs_error() which puts the whole FS to
RDONLY.
