[PATCH] rpcbind: fix leak of nconf in main()

Before reusing nconf in the getnetconfig() loop, we need to free the
memory that was previously allocated via getnetconfigent().  Fixes the
following leak reported by valgrind:

==9031== 1,136 (136 direct, 1,000 indirect) bytes in 1 blocks are definitely lost in loss record 63 of 67
==9031==    at 0x485183E: malloc (vg_replace_malloc.c:447)
==9031==    by 0x4879D1F: getnetconfigent (in /usr/lib64/libtirpc.so.3.0.0)
==9031==    by 0x4004336: main (rpcbind.c:271)
