video: ssd1307fb: Start page range at page_offset
[ Upstream commit dd9782834dd9dde3624ff1acea8859f3d3e792d4 ]
The page_offset was only applied to the end of the page range. This caused
the display updates to cause a scrolling effect on the display because the
amount of data written to the display did not match the range display
expected.
