When unbinding a channel from a tsg when virtual, vgpu_tsg_unbind_channel
would return an error if unbinding the channel on the guest side failed,
and did so before notifying the RM server of the unbind.
Later on in the recovery process, the guest OS would remove the channel from the
TSG's list, but this would leave the RM server with an out-of-date channel list.
Fix this by making the tsg_unbind_channel HAL optional and implemented only for vgpu:
the vgpu version now just notifies the RM server so that it can clean up its version
of the TSG; if vgpu, always call the tsg_unbind_channel HAL whether or not
the local unbind succeeded.

Replaced ch->mmu_debug_mode_enabled with ch->mmu_debug_mode_refcnt.
If channel is enabled multiple times by userspace, then ref count is
updated accordingly. There is an expectation that enable/disable
calls are balanced for setting channel's mmu debug mode.
When unbinding the channel, decrease refcnt for the channel until it
reaches 0.
Also, removed tsg parameter from nvgpu_tsg_set_mmu_debug_mode as it
can be retrieved from ch.

GPC MMU debug mode should be set if at least one channel
in the TSG has requested it. Add refcounting for MMU debug
mode, to make sure debug mode is disabled only when no
channel in the TSG is using it.

replace tsgid with a pointer to a struct tsg_gk20a in the function
gk20a_fifo_tsg_abort(). gk20a_fifo_tsg_abort needs to enumerate through
all the channels within the tsg as well as pass the tsg pointer to
other functions, qualifying the need to use a pointer instead as an
input parameter.
