- Add URTWN_WITHOUT_UCODE option (will disable any firmware specific code
when set).
- Do not exclude the driver from build when MK_SOURCELESS_UCODE is set
(URTWN_WITHOUT_UCODE will be enforced unconditionally).
- Do not abort initialization when firmware cannot be loaded;
behave like the URTWN_WITHOUT_UCODE option was set.
- Drop some unused variables from urtwn_softc structure.
Tested with RTL8188EU and RTL8188CUS in HOSTAP and STA modes.
