Ignore mobility headers if it is rejected by route optimization.
Mobility headers should be bypassed for any route optimization and
application should use transformation policy and wild-card states corerctly
to catch mobility headers prior than other packets.
This case which such reject is occurred may be either missing poilcy
or erroneous policy is inserted to kernel.
Based on MIPL2 kernel patch.
