[PATCH AUTOSEL 5.4 017/350] ath10k: add cleanup in ath10k_sta_state()

[Sasha Levin <sashal@kernel.org>]

From: Wenwen Wang <wenwen@cs.uga.edu>

[ Upstream commit 334f5b61a6f29834e881923b98d1e27e5ce9620d ]

If 'sta->tdls' is false, no cleanup is executed, leading to memory/resource
leaks, e.g., 'arsta->tx_stats'. To fix this issue, perform cleanup before
go to the 'exit' label.
