ippiMorphOpenBorder_8u_C1R is slower than older IPP version

[BaffledCoder]

Hello all,
Recently I shifted from IPP 5.3 to IPP 2021.6.2 and did a performance test following is the result.

	IPP 5.3.3.082	IPP 2021.6.2
	Time Per 1000 calls	Time Per 1000 calls	Percentage Decrease
ippiMorphOpenBorder_8u_C1R	4730.390188	6188.637276	-30.827

As you can see, for ippiMorphOpenBorder_8u_C1R, we are taking 30% more time as compared to IPP 5.3.
Whereas other functions like ippiDCTFwd_32f_C1R and ippiFFTFwd_RToPack_32f_C1R are faster by 40%.

Also, ippiMorphCloseBorder_8u_C1R is faster by 30%

My machine supports up to AVX2
