[rcu/kvfree: Eliminate k[v]free_rcu() single argument macro]
Removes the single-argument kvfree_rcu() and kfree_rcu() macros. Code
that would have previously used these single-argument kvfree_rcu() and
kfree_rcu() macros should instead use kvfree_rcu_mightsleep() or
kfree_rcu_mightsleep().
Use kfree_rcu_mightsleep() instead of kfree_rcu() if using Kernel-6.5 or
newer.

Due to changes in the host1x driver, dma_fence callbacks will be
executed in interrupt context instead of workqueue context as
previously. To allow for that, this patch effectively moves the
workqueue step into nvgpu so that the in-nvgpu fence callback gets
executed in workqueue context.

On host copy engine PBDMA interrupt, channel is aborted as part of the
recovery and its syncpt value is set to the max threshold.
Syncpoint may then get incremented by PBDMA (incr cmd gets processed)
after this interrupt is handled leading to syncpoint value becoming
greater than the max threshold.
Again while unbinding the channel, syncpoint value is incremented until
it reaches max threshold. Since syncpoint value is already greater than
max threshold, host1x version of nvgpu_nvhost_syncpt_set_minval will
loop for entire u32 range until it reaches max threshold and this
will hang the channel unbind.
nvgpu_nvhost_syncpt_set_minval can ensure the syncpoint value is greater
than or equal to max threshold. Hence update the check for syncpoint
value from not equal to less than.
