Add OFED and the associated options and drivers to x86 LINT builds:
- Mark 'sdp' as requiring 'inet'.
- Always include "opt_inet.h" and "opt_inet6.h" and modify the IB
driver Makefiles to honor WITH/WITHOUT_INET/INET6/_SUPPORT options
to determine what should be enabled during a module build.
- Fix the mlxen(4) driver and the core IB code to compile without
if INET is disabled (including when both INET and INET6 are disabled).
