Playback: remove special handling for Huawei (#7152)

This was introduced in 5105cdd to prevent crashes on Huawei phones[1].
However, it seems this has already regressed in 376ffed, where the setActive
call was moved outside of the try-catch block.

Additionally, the problem is now 9 years old, and hopefully fixed for the users
already.
