[PATCH AUTOSEL 4.19 186/206] wlcore: fix runtime pm imbalance in wl1271_tx_work

[Sasha Levin]

From: Dinghao Liu <dinghao.liu@xxxxxxxxxx>

[ Upstream commit 9604617e998b49f7695fea1479ed82421ef8c9f0 ]

There are two error handling paths in this functon. When
wlcore_tx_work_locked() returns an error code, we should
decrease the runtime PM usage counter the same way as the
error handling path beginning from pm_runtime_get_sync().
