[Mesa-stable] [PATCH] llvmpipe: (trivial) initialize src1_alpha var to NULL

[sroland at vmware.com]

From: Roland Scheidegger <sroland at vmware.com>

The blend code would do a conditional assignment based on it, causing valgrind
to complain. Since that variable was actually unused in this case, this
doesn't fix anything but the warning.
