media: camss: camss-video: Don't zero subdev format again after initi…

…alization

In an earlier commit, setting the which field of the subdev format struct
in video_get_subdev_format was moved to a designated initializer that also
zeroes all other fields. However, the memset call that was zeroing the
fields earlier was left in place, causing the which field to be cleared
after being set in the initializer.

Remove the memset call from video_get_subdev_format to avoid clearing the
initialized which field.
