[PATCH 2/2] XCB: Remove a wrong optimization [v2]

[Uli Schlachter]

Clear surfaces with an alpha channel are already replaced with a transparent
color in gstate, so this code was never hit. For surfaces without an alpha
channel, this optimization is only correct if the surface pattern has an extend
other than CAIRO_EXTEND_NONE.

Also, this belongs into gstate and some other commit will have to make sure
gstate does this.

This fixes the clear-source test for xcb.
