rpicamsrc: Clear intra-refresh MMAL param struct.

Browse source 
Use memset on the stack allocated MMAL_PARAMETER_VIDEO_INTRA_REFRESH_T
struct. Apparently mmal_port_parameter_get() doesn't retrieve all
parameters, causing random failures when we set the intra-refresh
param on the encoder.

Fixes https://github.com/thaytan/gst-rpicamsrc/issues/22 for me.
