    Adjust sctp_drain() definition to avoid clang 15 warning
    
    With clang 15, the following -Werror warning is produced:
    
        sys/netinet/sctp_pcb.c:6946:11: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        sctp_drain()
                  ^
                   void
    
    This is because sctp_drain() is declared with a (void) argument list,
    but defined with an empty argument list. Make the definition match the
    declaration.
