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)
INFO: ltp-pan reported some tests FAIL
