gpu: nvgpu: Simplify ref-counting on VMs
Simplify ref-counting on VMs: take a ref when a VM is bound to a
channel and drop a ref when a channel is freed.
Previously ref-counts were scattered over the driver. Also the CE
and CDE code would bind channels with custom rolled code. This was
because the gk20a_vm_bind_channel() function took an as_share as
the VM argument (the VM was then inferred from that as_share).
However, it is trivial to abtract that bit out and allow a central
bind channel function that just takes a VM and a channel.
