drivers: display: sdl: Fix asserts in sdl_display_write

The asserts and validation code were incorrectly mixing pitch and
width.  These incorrect checks were preventing rendering code from
re-using a smaller section of a buffer allocated to fit the full
screen. We expect to be able to update a portion of the display from a
portion of the buffer, in which case pitch must remain the screen
width. Expecting x + pitch to be smaller than the screen width is
incorrect.
