drm/etnaviv: fix dumping of iommuv2
etnaviv_iommuv2_dump_size(..) returns the number of PTE * SZ_4K but
etnaviv_iommuv2_dump(..) increments buf pointer even if there is no PTE.
This results in a bad buf pointer which gets used for memcpy(..), when
copying the MMU state in the coredump buffer.
Fixes: afb7b3b1deb4 ("drm/etnaviv: implement IOMMUv2 translation")
