Input: synaptics-rmi4 - fix video buffer size
commit 003f01c780020daa9a06dea1db495b553a868c29 upstream.
The video buffer used by the queue is a vb2_v4l2_buffer, not a plain
vb2_buffer. Using the wrong type causes the allocation of the buffer
storage to be too small, causing a out of bounds write when
__init_vb2_v4l2_buffer initializes the buffer.
