f2fs: fix to avoid use f2fs_bug_on() in f2fs_new_node_page()

As Dipanjan Das reported, syzkaller found a f2fs bug as below:

NAT entry and nat bitmap can be inconsistent, e.g. one nid is free in nat bitmap, and blkaddr in its NAT entry is not NULL_ADDR, it may trigger BUG_ON() in f2fs_new_node_page(), fix it.
