perf/x86: Move hybrid PMU initialization before x86_pmu_starting_cpu()

The current approach initializes hybrid PMU structures immediately before
registering them. This is risky as it can lead to key fields, such as
'capabilities', being inadvertently overwritten.

Although no issues have arisen so far, this method is not ideal. It makes
the PMU structure fields susceptible to being overwritten, especially with
future changes that might initialize fields like 'capabilities' within
init_hybrid_pmu() called by x86_pmu_starting_cpu().

To mitigate this potential problem, move the default hybrid structure
initialization before calling x86_pmu_starting_cpu().
