Defect Description:
	PHKL_26477:
	( SR:8606233690 CR:JAGae02914 )
	When trying to extend a vxfs filesystem beyond 128GB
	using fsadm(1M), the system will panic with a 'dirty
	inval' panic due to a failure to flush dirty smaps
	after updating the extent maps for the resize.

	Resolution:
	We now ensure that any dirty smaps are flushed after
	the extent maps are updated for resize.
