liboverlay: Fix stride alignment issue for s/w decoded video.

1. Due to alignment requirements on HAL_PIXEL_FORMAT_YV12 format,
rotator buffer size calculation needs to be performed based on
rotated width and height because buffer size can be different when
width & height are swapped due to 90 degree rotation.

2. Input and output color formats are same for MDSS Rotator.
