libext2fs: enforce a max nested link count in ext2fs_find_block_device()

Define EXT2FS_MAX_NESTED_LINKS as 8, and check the link count to make
sure we don't exceed it in ext2fs_find_block_device() and
follow_link(). This fixes a potential infinite loop in
ext2fs_find_block_device() if there are symbolic loop links in the
device directory.
