[PATCH bpf-next] bpf: Avoid unnecessary audit log for CPU security mitigations

[Yafang Shao <laoar.shao@xxxxxxxxx>]

Check cpu_mitigations_off() first to avoid calling capable() if it is off. 
This can avoid unnecessary audit log.

Fixes: bc5bc309db45 ("bpf: Inherit system settings for CPU security mitigations")
