Remove struct pmchdr_cpuidinfo which was just a wrapper around a
flexible array member of uint32_t. Flexible array members are
non-standard in C++, and even in C are not allowed as the only member
of a struct.
GCC errored out on pmchdr_cpuidinfo, but did not complain about
pmchdr_pmcinfo, so I left it alone here, though it is also non-standard.
Fixes: 93da997ef7 ("pmc: new pmc log processing framework")
