f2fs: remove WARN_ON in f2fs_is_valid_blkaddr
Syzbot triggers two WARNs in f2fs_is_valid_blkaddr and
__is_bitmap_valid. For example, in f2fs_is_valid_blkaddr,
if type is DATA_GENERIC_ENHANCE or DATA_GENERIC_ENHANCE_READ,
it invokes WARN_ON if blkaddr is not in the right range.
The call trace is as follows:
f2fs_get_node_info+0x45f/0x1070
read_node_page+0x577/0x1190
__get_node_page.part.0+0x9e/0x10e0
__get_node_page
f2fs_get_node_page+0x109/0x180
do_read_inode
f2fs_iget+0x2a5/0x58b0
f2fs_fill_super+0x3b39/0x7ca0
Fix these two WARNs by replacing WARN_ON with dump_stack.
