ath10k: Fix error handling in case of CE pipe init failure

[ Upstream commit 31561e8557cd1eeba5806ac9ce820f8323b2201b ]

Currently if the copy engine pipe init fails for snoc based
chipsets, the rri is not freed.

Fix this error handling for copy engine pipe init
failure.

Tested-on: WCN3990 hw1.0 SNOC WLAN.HL.3.1-01040-QCAHLSWMTPLZ-1
