This issue is reported in TLV-299.
This commit fixed allocate_cmdbuf may infinite loop
and leak of release the cmdbuf only reserved but not
link_and_run.
If cmdbuf not run done when release,do not firstly abort,
instead wait done event reduce abort failed.
Add cmdbuf id and line info for error log.
Fixed busy count record idle twice in read module all
regs issue.

The GPU is halted when it hits a MMU exception, so there is no point in
waiting for the job timeout to expire or try to work out if the GPU is
still making progress in the timeout handler, as we know that the GPU
won't make any more progress.

Now that it is only used to track the driver internal state of
the MMU global and cmdbuf objects, we can get rid of this property
by making the free/finit functions of those objects safe to call
on an uninitialized object.
