Camera: fix kernel warning after VI timeout

Browse Source 
VI return timeout status when no frames are
received from camera sensor. During the error
recovery, the v4l2 buffers are set to
VB2_BUF_STATE_ERROR, this causes kernel warning.
As per the v4l2 framework correct buffer state
for timeout is VB2_BUF_STATE_QUEUED.
