Revert "gallium: specify resource_resolve destination via a pipe_surface"

This reverts commit 5d5af7d359e0060fa00b90a8f04900b96f9058b0.

It turns out the issue this was supposed to fix merely counter-acted
a bug in the hardware driver that I wasn't aware of.

The resource_resolve is not supposed to do sRGB conversion, period.
(This would violate the requirement that source and destination must
be of the same format).
