[Mesa-stable] [PATCH 1/2] radeon: fix bgrx8/xrgb8 blits

[sroland at vmware.com]

From: Roland Scheidegger <sroland at vmware.com>

Since d21320f6258b2e1780a15c1ca718963d8a15ca18 the same txformat table entries
are used for "normal" texturing as well as for blits. However, I forgot to put
in an entry for the bgrx8 (le) and xrgb8 (be) formats - the normal texturing
path can't hit them because the radeon tex format chooser will never chose
them, but we get that format from the dri buffers (at least I assume we got
it from there). This caused lots of piglit regressions (and probably lots of
trouble outside piglit too).
This fixes bug https://bugs.freedesktop.org/show_bug.cgi?id=92900.
