Konsta Holtta 6e22f39e87 gpu: nvpgu: cde: fix timeout mgmt, use two lists ...

If a channel timeout occurs, reload only the particular context/channel
where the timeout occurred, instead of destroying whole cde. Reloading
happens by allocating a replacement context and marking the offending
channel as soon-to-be-deleted.

Clean up the code by using two separate lists for free and used
contexts. Rename channel deallocation/allocation functions to better
describe what they do, and annotate the functions that need locking.

Also do not wait for channel idle before submitting, since the acquired
context has a ready channel already.
