When using CDE firmware v1, combine H and V swizzling passes into one

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.

Instead of current preallocated array plus dynamically allocated
temporary contexts, use a linked list in LRU fashion, always storing
free contexts at the beginning of the list. Initialize the preallocated
contexts to the list and store dynamically allocated temporaries there
too for quick reuse as needed, with a delayed scheduled work for
deleting temporaries when the high load has diminished.

When preparing a new job, loop initially through the small number of
preallocated contexts and try to find one that is already finished,
instead of blindly getting the next slot in lru order. If all have work
to do, select next in lru order. This reduces the possibility of a
deadlock between cde tasks.
