RecorderBase: fix Coverity ID 1420182 Unchecked dynamic_cast
If the dynamic_cast fails, a null pointer dereference will occur; if the
dynamic_cast cannot fail, using static_cast instead offers better performance.

In RecorderBase::CreateRecorder(TVRec *, ChannelBase *, RecordingProfile const &,
GeneralDBOptions const &): Dynamic_cast may fail and return null if the type cast
is incompatible.
