media: vimc: zero the media_device on probe
The media_device is part of a static global vimc_device struct.
The media framework expects this to be zeroed before it is
used, however, since this is a global this is not the case if
vimc is unbound and then bound again.
So call memset to ensure any left-over values are cleared.
