[PATCH 7/8] media: atomisp: add return codes for pipeline config functions

From: Mauro Carvalho Chehab
Date: Fri Nov 05 2021 - 13:48:24 EST

Those functions can internally break, but, as they don't return
errors, internally there are some assert() calls, which is bad,
as it hangs the driver.

So, add return codes there, in preparation for removing such
assert() calls.
