Subject: [PATCH 4.19 187/346] ath10k: Fix an error handling path

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

[ Upstream commit ed3573bc3943c27d2d8e405a242f87ed14572ca1 ]

If 'ath10k_usb_create()' fails, we should release some resources and report
an error instead of silently continuing.
