Revert "ipv6: defrag: drop non-last frags smaller than min mtu" 



This reverts commit 5f2d68b6.

The change drops the non-last fragments whose size is less
than min mtu, this is currently breaking MT call on IWLAN.
It is observed that the SIP_INVITE has fragments of size
less than min mtu, currently reverting the change to allow
MT call to go through.
