COMPMID-2336: Fix validation for quantized NEDepthwiseConvolutionLayer

Assertions from calculate_quantized_multiplier_less_than_one were not
captured resulting in incorrect computation being performed on invalid
inputs.

This patch also fixes a discrepancy between the interfaces of validate
and configure methods of NEDirectConvolutionLayerOutputStageKernel.
