cam: kms_sink: Make lifetime management of DRM request safer
The drmRequest is KMSSink::processRequest() is created as a naked pointer, passed to the constructor of the KMSSink::Request object that stores it in a std::unique_ptr<>, and used later in the function. The current implementation is safe, but could be prone to both memory leaks and use-after-free bugs if modified. Improve it by replacing the naked pointer with a std::unique_ptr<>.
