[PATCH v2] sched: sched_domain fix highest_flag_domain function

[Xuewen Yan]

the highest_flag_domain is to search the highest sched_domain
containing flag, but if the lower sched_domain didn't contain
the flag, but the higher sched_domain contains the flag, the
function will return NULL instead of the higher sched_domain.

For example:
In MC domain : no SD_ASYM_CPUCAPACITY flag;
In DIE domain : containing SD_ASYM_CPUCAPACITY flag;
the "highest_flag_domain(cpu, SD_ASYM_CPUCAPACITY)" will return NULL.
