android: Protect against null callbacks
According to the Android camera HAL C interface documentation, the
camera service is supposed to set callbacks after initializing the HAL
and calling get_number_of_cameras(), before any other calls to the
module. We rely on this behaviour and use callbacks unconditionally,
which would lead to a crash if the camera service behaved incorrectly.
While the camera service isn't supposed to behave incorrectly,
gracefully handling the error when opening cameras isn't costly, and
provides better diagnostic than a crash.
While at it, removed an unneeded [[maybe_unused]] attribute.
