Subject: [PATCH 4.18 122/228] ath10k: snoc: use correct bus-specific pointer in RX retry

4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Brian Norris <briannorris@...omium.org>

[ Upstream commit 426a0f0b5a2fe1df3496ba299ee3521159dba302 ]

We're 'ath10k_snoc', not 'ath10k_pci'. This probably means we're
accessing junk data in ath10k_snoc_rx_replenish_retry(), unless
'ath10k_snoc' and 'ath10k_pci' happen to have very similar struct
layouts.

Noticed by inspection.
