Aneesh Kumar K.V b939e3766e ext4: Use the ext4_ext_actual_len() helper function 
ext4 uses the high bit of the extent length to encode whether the extent
is intialized or not. The helper function ext4_ext_get_actual_len should
be used to get the actual length of the extent.

This addresses the kernel bug documented here: 
     http://bugzilla.kernel.org/show_bug.cgi?id=9732

kernel BUG at fs/ext4/extents.c:1056!
