Subject: [PATCH] Fix segfault on rotation while recording

The packet sink push_session() callback is optional, but it was called
unconditionnally even when not implemented, leading to a segfault.

Bug introduced by commit 78cba1b7c29fe45057d180a183ce7efcd7044106.

Fixes #6687 <https://github.com/Genymobile/scrcpy/issues/6687>
