[ Upstream commit 855af2d74c870d747bf53509f8b2d7b9dc9ee2c3 ]
When h5_close() is called, h5 is directly freed when !hu->serdev.
However, h5->rx_skb is not freed, which causes a memory leak.
Freeing h5->rx_skb and setting it to NULL, fixes this memory leak.
Fixes: ce945552fde4 ("Bluetooth: hci_h5: Add support for serdev enumerated
devices")
