It is the job of the ppc_radix64_get_fully_qualified_addr() function which is called at the beginning of ppc_radix64_xlate() to set both lpid *and* pid. It doesn't buy us anything to initialize them first. Worse, a bug in ppc_radix64_get_fully_qualified_addr(), eg. failing to set either lpid or pid, would be undetectable by static analysis tools like coverity. Some recent versions of gcc (eg. gcc-9.3.1-2.fc30) may still think that lpid or pid is used uninitialized though, so this also adds default cases in the switch statements to make it clear this cannot happen.
