[ 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

Fixes: 4945af5b264f ("ath10k: enable SRRI/DRRI support on ddr for WCN3990")
