Revert "sched: Enable HMP priority filter by default"

This reverts commit 68315334e32932739145ddb41a46cc86b8b056b3.

Having the priority filter enabled prevents proper operation
on Android systems where a wider range of priorities are used
by userspace to partition types of tasks. Those tasks should still
be able to benefit from the use of big CPUs when required.
