On deleting the subcontext, tsg->subctx_vms[] entries are set to NULL as
per the subcontext id. For async subcontexts the index logic was used
from that of tsg->async_veids bitmask. However subctx_vms is an array
shared by all subcontexts hence index should be subcontext id aka veid.

Also update the description of function nvgpu_tsg_validate_ch_subctx_vm
as some of the functionality is now moved to another function
nvgpu_tsg_create_sync_subcontext_internal.

specification wherein dma-buf reservation is to be locked while

With this, we can enable compression for all kernel versions that
was disabled earlier for v6.2+ kernels.

a5640d61bd gpu: nvgpu: free VEID if the channel is closed 
In case of process crash or forceful closure of the channels, userspace
may not release the VEID. In that case, creating further subcontexts
may not be possible.

Hence, when the channel is closed forcibly (linux), release the VEID on
closure of the last channel in the subcontext.

With this, normally on linux, channel close will not relase the VEID
However, on qnx it will release the VEID. So delete subcontext devctl
call on qnx will be nop in normal case hence changed the error print
and error return to success.

Also added check in the subcontext delete ioctl fn that all channels
are unbound before deleting the subcontext. This is to ensure that
channels don't refer to dangling subcontext pointer.

9b58826f97 gpu: nvgpu: Fix build for Linux without virtualization 
L4T does not support virtualization currently and so we should be able
to build NVGPU without virtualization support. This avoids having to
build many virtualization drivers for Tegra.

The build flag CONFIG_TEGRA_VIRTUALIZATION was added for building
out-of-tree drivers to select if virtualization is enabled or not. This
is enabled by default. However, if this is not set, then driver should
still build. Currently, NVGPU is not building when
CONFIG_TEGRA_VIRTUALIZATION is not set because
CONFIG_TEGRA_GR_VIRTUALIZATION is now always enabled for NVGPU. Fix this
by wrapping CONFIG_TEGRA_GR_VIRTUALIZATION with
CONFIG_TEGRA_VIRTUALIZATION.
