etnaviv: always use RS align when GPU has TEXTURE_HALIGN feature

etnaviv: always use RS align when GPU has TEXTURE_HALIGN feature

Due to a logic bug we didn't always up-align the resource when the GPU
has the TEXTURE_HALIGN feature, which broke the RS blit when we need
to blit into a sampler shadow from a multi-tiled render target.
