Add proper type cast (char *) to the buffer being passed to TH_LOG macro in __recvpair function.
This change fixes the below warnings during test compilation:
In file included from msg_oob.c:14: msg_oob.c: In function ‘__recvpair’: ../../kselftest_harness.h:106:40: warning: format ‘%s’ expects argument of type ‘char *’,but argument 6 has type ‘const void *’ [-Wformat=] ../../kselftest_harness.h:101:17: note: in expansion of macro ‘__TH_LOG’ msg_oob.c:235:17: note: in expansion of macro ‘TH_LOG’ ../../kselftest_harness.h:106:40: warning: format ‘%s’ expects argument of type ‘char *’,but argument 6 has type ‘const void *’ [-Wformat=] ../../kselftest_harness.h:101:17: note: in expansion of macro ‘__TH_LOG’ msg_oob.c:259:25: note: in expansion of macro ‘TH_LOG’
Fixes: tag is needed here (no space between SOB tag)

I don't remember why I defined expected_buf as (void *), but more simple fix would be the following ?
