When calling ia_css_pipeline_create_and_add_stage() function, there's no
condition to check whether ia_css_pipeline_create_and_add_stage() throw
an error or not. So add conditional check for the return value of
ia_css_pipeline_create_and_add_stage() function.

This is reported by Coverity Scan with CID 1408952 as UNUSED_VALUE.

I am not sure if omitting the error check is intentional or not, but from
what I see from another ia_css_pipeline_create_and_add_stage() usage
in the same function, we check the return value after the call and return
the error code if it's non-zero.

I also don't have the device to test this change.

Oh I didn't know that we need to add Fixes tag too. Alright, I will add
Fixes tag in the next iteration of the patch.

Thank you for the feedback.
