di_flags2 is initialized to zero for v4 and earlier file systems. This
means di_flags2 can only be non-zero for a v5 file systems, in which
case both the parent and child inodes can store the filed. Remove the
extra di_version check, and also remove the rather pointless local
di_flags2 variable while at it.
