pvr: fix mipmap size calculation for bc formats

The block size given by vk_format_get_blocksize is in blocks, not
texels.

dEQP tests affected:
  dEQP-VK.pipeline.monolithic.image_view.view_type*
    .format.eac*lod_base_mip_level

Fixes: 8991e6464 ("pvr: Add a Vulkan driver for Imagination Technologies PowerVR Rogue GPUs")
