btrfs: subpage: remove the unused error bitmap dumping

Since commit 2b2553f12355 ("btrfs: stop setting PageError in the data I/O
path") btrfs no longer utilizes subpage error bitmaps anymore, but the
commit forgot to remove the error bitmap in btrfs_subpage_dump_bitmap(),
resulting in possible meaningless result for the error bitmap.

Fix it by just removing the error bitmap dumping.
