    ipfilter: simplify ipf_proxy_check() return codes
    
    ipf_proxy_check() returns -1 for an error and 0 or 1 for success.
    ipf_proxy_check()'s callers check for error and if the return code
    is 0, they change it to 1 prior to returning to their callers. Simply
    by returning -1 or 1 we reduce complexity and cycles burned changing
    0 to 1.
    
    (cherry picked from commit 874b1a35486b570513680c3d456b062ba097e1d9)
