[PATCH] perf pmu: add loaded_json_aliases for non-core pmu when get total events number

[Xu Yang <xu.yang_2@nxp.com>]

After pmu_read_sysfs(), event aliases in json may be loaded for non-core
pmu. And pmu->event_table is NULL for non-core pmu.
If perf_pmu__num_events() didn't add loaded_json_aliases to the total
number, perf list will show below error:

Unexpected event imx8_ddr0/imx8_ddr0/write-command//
...

This is because perf_pmu__num_events() didn't count correct events number.
This will allow perf_pmu__num_events() to get corrent events number.
