pseries: Fix initialization of sPAPREnvironment structure
Since we added PCI support to the pseries machine, we include a qlist of PCI host bridges in the sPAPREnvironment structure. However this list was never properly initialized it. Somehow we got away with this until some other recent change broke it, and we now segfault immediately on startup. This patch adds the required QLIST_INIT(), and while we're at it makes sure we initialize the rest of the sPAPREnvironment structure to 0, to avoid future nasty surprises.
