[LTP] [PATCH] syscalls/bind01: Close/recreate inet_socket after calling bind() successed

[Zhao Gongyi]

When the test running with -i option to run more than one time,
it will fail because of calling bind successed more than one time,
as follows:

#bind01 -i 2
tst_test.c:1313: TINFO: Timeout per run is 0h 05m 00s
bind01.c:52: TPASS: invalid salen: EINVAL (22)
bind01.c:52: TPASS: invalid socket: ENOTSOCK (88)
bind01.c:55: TPASS: INADDR_ANYPORT passed
bind01.c:52: TPASS: UNIX-domain of current directory: EAFNOSUPPORT (97)
bind01.c:52: TPASS: non-local address: EADDRNOTAVAIL (99)
bind01.c:52: TPASS: invalid salen: EINVAL (22)
bind01.c:52: TPASS: invalid socket: ENOTSOCK (88)

bind01.c:52: TPASS: UNIX-domain of current directory: EAFNOSUPPORT (97)
bind01.c:52: TPASS: non-local address: EADDRNOTAVAIL (99)
