This is a fix for issue with id 746-001125: Tanaro: Bluetooth does not work

Bluetooth: hci_uart: add missing NULL check in h5_enqueue
[ Upstream commit 32cb08e958696908a9aad5e49a78d74f7e32fffb ]
Syzbot hit general protection fault in __pm_runtime_resume(). The problem
was in missing NULL check.
hu->serdev can be NULL and we should not blindly pass &serdev->dev
somewhere, since it will cause GPF.
