[PATCH v2 2/4] libcamera: software_isp: Drop unnecessary sanity check

[Umang Jain]

Currently the soft-isp outputs a single output stream. Hence,
drop the unnecessary check for stream indexes.

Another reason to drop is actually the stream indexes is meant to be
unique in outputs std::map<>, hence checking for unique stream indexes
is redundant.
