[PATCH 5.15] media: atomisp: sh_css: check ia_css_pipeline_create_and_add_stage() return code

[PATCH 5.15] media: atomisp: sh_css: check ia_css_pipeline_create_and_add_stage() return code

[Alexandra Diupina]

commit 912680064f94 ("media: atomisp: make sh_css similar to Intel Aero driver")
removes the affected code, but in versions
tags/v5.8-rc1~10^2~220 - tags/v5.17-rc1~114^2~261
there is no check for the return value of the
ia_css_pipeline_create_and_add_stage() function.

ia_css_pipeline_create_and_add_stage() may return an
error code, so check and return it on error.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: 7796e455170e ("media: staging: media: atomisp: Fix alignment and line length issues")
