msdkenc: close encoder upon bitrate change

Browse source 
Upon bitrate change, make sure to close the encoder otherwise
the encoder is not re-initialized and the target bitrate is
never reached, and the encoder was flushed at each frame
from this moment.

Regression introduced in f2b35abcab which replaced the call
that was closing the encoder by an early return to avoid
re-initialization.
