msm_fb: Correct mdp_iommu array size to avoid scribbling
The mdp_iommu array was undersized. This resulted in scribbling of
nearby data structures which, through a long series of events,
lead to invalid pointer dereferences in the workqueue framework's
process_one_work() function on (at least) the 8930 SoC.
