ath10k-firmware: update Candela Tech firmware images

*  Jan 2, 2019
Rebase patches to make 9980 bisectable.

*  Jan 2, 2019
Fix scheduling related assert when wal-peer is deleted with pending
tx buffers (bug 54, and others)

*  Jan 7, 2019:
Fix specifying retransmits for AMPDU frames.  It was previously ignored
since it is a 'software' retransmit instead of a hardware retransmit.

*  Jan 9, 2019
Fix potential way to get zero rates selected (and then assert)

*  Jan 18, 2019
pfsched has specific work-around to just return if we find invalid flags AND
if we are in an out-of-order situation.  Maybe this is last of the pfsched
related issues (bug 54 and similar).

The rcSibUpdate method can be called concurrently with IRQ tx-completion callback,
and that could potentially allow the tx-completion callback to see invalid state
and assert or otherwise mess up the rate-ctrl logic.  So, disable IRQs in
rcSibUpdate to prevent this.  Related to bug 58.

*  Jan 28, 2019
Ensure that cached config is applied to ratectrl objects when fetched from
the cache.  This should fix part of bug 58.

*  Jan 28, 2019
Ensure that ratectrl objects from cachemgr are always initialized.  This fixes
another part of bug 58.

*  Jan 30, 2019
Better use of temporary rate-ctrl object.  Make sure it is initialized, simplify
code path.  This finishes up porting forward similar changes I made for wave-1
firmware long ago, and fixes another potential way to hit bug-58 issues.

*  Jan 30, 2019
Cachemgr did not have a callback for when memory was logically freed.  This means
that peers could keep stale references to rate-ctrl objects that were in process
of being DMA'd into to load a different peer's rate-ctrl state.  This was causing
the bugcheck logic to fail early and often, and I suspect it might be a root cause
of bug 58 as well.  The fix is to add a callback and set any 'deleted' memory references
to NULL so that we cannot access it accidentally.  Thanks to excellent logs and patience
from the bug-58 reporter!
