[ Upstream commit 8cc782cd997dc4eb3ac183228d563727884ba874 ]
If the call to hw_init() fails for any of the drivers, the driver will leak memory that was allocated in BT coexistence setup. Technically, each of the drivers should have done this free; however placing it in rtl_pci fixes all the drivers with only a single patch.
