Fix Coverity warnings regarding r293229

Browse source 
rpcbind/check_bound.c
	Fix CID1347798, a memory leak in mergeaddr.

rpcbind/tests/addrmerge_test.c
	Fix CID1347800 through CID1347803, memory leaks in ATF tests.  They
	are harmless because each ATF test case runs in its own process, but
	they are trivial to fix.  Fix a few other leaks that Coverity didn't
	detect, too.
