IP Pipeline application with the configuration for Flow Classification IPV6 did 
not instantiate.
Parse error in section "PIPELINE1": entry "dma_src_mask" too long

The dma_src_mask check in pipeline_passthrough_parse_args() is wrong.

This fix increases the length of dma_src_mask by 1 for NULL termination
and corrected the validation of dma_src_mask length.
This fix is also propagated to pipeline_fc_parse_args() for key_mask_str 
validation.
