conf: Plug memory leaks on virDomainDiskDefParseXML 

Detected by valgrind. Leaks are introduced in commit b22eaa7.

* src/conf/domain_conf.c (virDomainDiskDefParseXML): fix memory leaks.

How to reproduce?

% make && make -C tests check TESTS=qemuxml2argvtest
% cd tests && valgrind -v --leak-check=full ./qemuxml2argvtest

actual result:

==2143== 12 bytes in 2 blocks are definitely lost in loss record 74 of 179
