KVM: x86: use the KVM side max supported fixed counter
KVM vPMU doesn't support to emulate all the fixed counters that the
host PMU driver has supported, e.g. the fixed counter 3 used by
Topdown metrics hasn't been supported by KVM so far.
Rename MAX_FIXED_COUNTERS to KVM_PMC_MAX_FIXED to have a more
straightforward naming convention as INTEL_PMC_MAX_FIXED used by the
host PMU driver, and fix vPMU to use the KVM side KVM_PMC_MAX_FIXED
for the virtual fixed counter emulation, instead of the host side
INTEL_PMC_MAX_FIXED.
