DumbFB: fix dumb buffer alloc for omap NV12
Dividing the bitspp with xsub works better than dividing the width, as
otherwise the buffer stride will get aligned easily quite a bit. This is
somewhat OMAP specific fix/work-around, but then, it's not clear how
NV12 buffer sizes should be calculated anyway.
