drm/msm/dsi: Flip greater-than check for slice_count and slice_per_intf

[ Upstream commit 82e72fd2 ]

According to downstream /and the comment copied from it/ this comparison
should be the other way around.  In other words, when the panel driver
requests to use more slices per packet than what could be sent over this
interface, it is bumped down to only use a single slice per packet (and
strangely not the number of slices that could fit on the interface).
