Definitions by which copy engine structure are
allocated do not change so it doesn't make much
sense to re-create those structures each time
device is booted (e.g. due to firmware recovery).
This should decrease chance of memory allocation
failures.
While at it remove per_transfer_context pointer
indirection. The array has been trailing the copy
engine ringbuffer structure anyway. This also
saves pointer size worth of bytes for each copy
engine ringbuffer.

v2:
* mention per_transfer_context update in the
commit message (Kalle)
* split ath10k_pci_ce_deinit() move into a
separate patch for easier regression testing
