Subject: [PATCH 06/10] bna: IOC uninit check and misc cleanup

Chnage details:
	- Added a check in ioc firmware lock function to see if IOC is in BFI_IOC_UNINIT state or not. If it is not in UNINIT
state and the last IOC boot was not done by OS driver, force IOC state to BFI_IOC_UNINIT
	- Unused macro and API cleanup
