[PATCH RFT v2] media: atomisp: Add error check in create_host_regular_capture_pipeline()

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.

v1 -> v2: Add Fixes tag (suggested by Dan Carpenter).

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.
