This fixes a problem where the destination has a DCC-incompatible view
format and triggers a DCC decompression using a custom u_blitter path, which
is disallowed inside u_blitter due to it being a u_blitter recursion that
always crashes.
This is also better because we'll get the best codepath (u_blitter or
compute) instead of just u_blitter,
