Bluetooth: hci_uart: fix GPF in h5_recv
[ Upstream commit 2fc7acb69fa3573d4bf7a90c323296d840daf330 ]
Syzbot hit general protection fault in h5_recv(). The problem was in
missing NULL check.
hu->serdev can be NULL and we cannot blindly pass &serdev->dev
somewhere, since it can cause GPF.
Fixes: d9dd833cf6d2 ("Bluetooth: hci_h5: Add runtime suspend")
