i965: Don't use fast copy blit in case of logical operations other than GL_COPY
XY_FAST_COPY_BLT command doesn't have a field for raster operation. So, fall
back to using XY_SRC_COPY_BLT to handle those cases.
Fixes piglit test gl-1.1-xor-copypixels when fast copy blit is enabled
for all tiling formats.
