    ofed/infiniband: fix ifdefs for new INET changes, fixing LINT-NOIP
    
    Some of the ofed/infiniband code has INET and INET6 address handling
    code without using ifdefs.  This failed with a recent change to INET,
    in which IN_LOOPBACK() started using a VNET variable, and which is not
    present if INET is not configured.  Add #ifdef INET, and INET6 for good
    measure, in cma_loopback_addr(), along with inclusion of the options
    headers in ib_cma.c.
