Revert "video: respect stride alignment when calculating planes offsets"

Browse Source 
This reverts commit 28e1dadbfaa403679e69f8173d1aa2c7500fd556.

Incrementing the offset to make the plane aligned causes the image to be
incompatible with what Xv expects. Rather that forcing a memcpy in the
xvimagesink we would like to do adjust the left padding instead.
