Josep Torra f2c75d548d msdkenc: handle bitrate changes in playing state 
When the bitrate is changed in playing state the encoder issues a reconfig
that drains and recreates the underlaying hw encoder instance.
With this set of changes we ensure that all this work is only made when
the bitrate did actually change. It also tries to reuse the vpp buffer
pool and fixes the pool leak spotted when testing this feature.
