Calvin Owens b489556a85 Bluetooth: fix corruption in h4_recv_buf() after cleanup 
A different structure is stored in drvdata for the drivers which used
that duplicate function, but h4_recv_buf() assumes drvdata is always an
hci_uart structure.

Consequently, alignment and padding are now randomly corrupted for
btmtkuart, btnxpuart, and bpa10x in h4_recv_buf(), causing erratic
breakage.

Fix this by making the hci_uart structure the explicit argument to
h4_recv_buf(). Every caller already has a reference to hci_uart, and
already obtains the hci_hdev reference through it, so this actually
eliminates a redundant pointer indirection for all existing callers.
