mt76: mt7615: Fix memory leak in mt7615_mcu_wtbl_sta_add()

Browse source

[ Upstream commit 53d1548612 ]

In mt7615_mcu_wtbl_sta_add(), an skb sskb is allocated. If the
subsequent call to mt76_connac_mcu_alloc_wtbl_req() fails, the function
returns an error without freeing sskb, leading to a memory leak.

Fix this by calling dev_kfree_skb() on sskb in the error handling path
to ensure it is properly released.
