drm/amdkfd: Fixed kfd_process cleanup on module exit.

Browse source

[ Upstream commit 20bc9f76b6 ]

Handle case when module is unloaded (kfd_exit) before a process space
(mm_struct) is released.

v2: Fixed potential race conditions by removing all kfd_process from
the process table first, then working on releasing the resources.

v3: Fixed loop element access / synchronization.  Fixed extra empty lines.
