selinux: Fix ltp test connect-syscall failure
Fix the following error when running regression tests using LTP as follows:
cd /opt/ltp/
cat runtest/syscalls |grep connect01>runtest/connect-syscall
./runltp -pq -f connect-syscall
Running tests.......
connect01 1 TPASS : bad file descriptor successful
connect01 2 TPASS : invalid socket buffer successful
connect01 3 TPASS : invalid salen successful
connect01 4 TPASS : invalid socket successful
connect01 5 TPASS : already connected successful
connect01 6 TPASS : connection refused successful
connect01 7 TFAIL : connect01.c:146: invalid address family ;
returned -1 (expected -1), errno 22 (expected 97)
