etnaviv: rs: fix MSAA alignment adjustment

Browse source 
The RS window alignment restrictions apply to the downsampled side of the
blit, so we must increase the blit size alignment by the MSAA scale to
avoid RS hangs. If a multi-pipe resolve is used (when the GPU doesn't have
the singlebuffer feature) then the Y alignment needs to be increased by
the number of pixel pipes.

The resource allocation has already been fixed to take this additional
alignment requirement into account.
