There has been a recent change to the new powervr KMD to always zero buffer objects at allocation time to avoid information leaks. This change was made to address upstream feedback [1]. The result is that the PVR_WINSYS_BO_FLAG_ZERO_ON_ALLOC no longer makes a difference when using this KMD. As the powervr KMD is the one we actually care about, it makes sense to mirror this change when using the downstream pvrsrvkm KMD in order to avoid differences in behaviour between the two KMDs. As this makes the PVR_WINSYS_BO_FLAG_ZERO_ON_ALLOC flag entirely redundant, remove it.
