V4L/DVB: V4L2: Replace loops for finding max buffers in VIDIOC_REQBUFS callbacks
Due to obvious copy and paste coding a number of video capture drivers
which implement a limit on the buffer memory decremented the user
supplied buffer count in a while loop until it reaches an acceptable
value.
This is a silly thing to do when the maximum value can be directly
computed.
