This reverts commitbb4291dcac. This change causes KFDTest failed on gfx803. The first hsaKmtCreateEvent call allocate system memory for events_page because global variable events_page is NULL. And this events page vm address should not be freed until the process exit. The change to destrory objects in hsaKmtCloseKFD removes events page. As a result, KFDTest call hsaKmtOpenKFD again and then allocate memory will get same events_page vm address on gfx803, and map this vm failed because the vm conflict with events_page mapping. KFDTest passed on VG10, gfx906 because allocate memory get different vm address. hsaKmtCreateEvent still works fine as the driver keeps the events page mapping of the process. We should only destroy objects in fork cloned child process regardless if gpu_vm is NULL or not.
