Subject: [PATCH 4.14 123/242] ath10k: Release some resources in an error handling path

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit 6364e693f4a7a89a2fb3dd2cbd6cc06d5fd6e26d ]

Should an error occur after calling 'ath10k_usb_create()', it should be
undone by a corresponding 'ath10k_usb_destroy()' call

Fixes: 4db66499df91 ("ath10k: add initial USB support")
