gallium/u_transfer_helper: Fix MSAA mappings with nonzero x/y.

We created a temporary with box->{width,height} and then tried to map
width,height from a nonzero offset when we meant to just map the whole
temporary.

Fixes segfaults in V3D in dEQP-GLES3.functional.prerequisite.read_pixels
with --deqp-egl-config-name=rgba8888d24s8ms4 and also piglit's read-front
clear-front-first -samples=4
