drm/nouveau/bios: set info only when the return is not 0
clang static analysis reports
drivers/gpu/drm/nouveau/nvkm/subdev/bios/pmu.c:68:17: warning: The right operand of '*' is a garbage value [core.UndefinedBinaryOperatorResult]
switch (!!data * *ver) {
^ ~~~~
A switch statement with only a default should be reduced to an if.
If nvbios_pmuEp() returns 0, via the data variable, the output info parameter
is not used. So set info only when data is not 0.
The struct nvbios_pmuE only has the type and data elements. Since both of these
are explicitly set, memset is not needed. So remove it.
