amdkfd: process pointer of a HIQ should be NULL

Browse Source 
In kq_initialize, queue->process of a HIQ should
be NULL as initialized, because it does not belong
to any kfd_process.

This commit decommisions the function kfd_get_process() because
it can not locate a specific kfd_process among multiple
contexts and not any code path calls it after this commit.
