[PATCH v1] Documentation: guides: application-developer: Fix variable shadowing

[Barnabás Pőcze]

The mentioned commit mistakenly introduced a new variable for storing
the camera instead of just assigining to the global variable defined
earlier in the tutorial. Fix that by making it an assignment.
