ext4: Add null extent check to ext_get_path There is the possibility that path structure which is taken by ext4_ext_find_extent() indicates null extents. Because during data block exchanging in ext4_move_extents(), constitution of an extent tree may be changed. As a solution, the patch adds null extent check to ext_get_path().
