amdkfd: properly free secondary context id

Browse Source 
Function kfd_process_free_id() should skip over
the primary kfd process because its context id
is fixed assigned, not allocated through the ida table.
This function should only work on secondary contexts.

Fixes: fac682a1d1 ("amdkfd: identify a secondary kfd process by its id")
