f2fs: fix a bug caused by NULL extent tree
commit dad48e73127ba10279ea33e6dbc8d3905c4d31c0 upstream.
Thread A: Thread B:
-f2fs_remount
-sbi->mount_opt.opt = 0;
<--- -f2fs_iget
-do_read_inode
-f2fs_init_extent_tree
-F2FS_I(inode)->extent_tree is NULL
-default_options && parse_options
-remount return
<--- -f2fs_map_blocks
-f2fs_lookup_extent_tree
-f2fs_bug_on(sbi, !et);
The same problem with f2fs_new_inode.
