remote: fix jump depends on uninitialised value
Currently remote driver only initializes partial fields of remote_connect_get_all_domain_stats_args. But xdr_array() will check the uninitialised field 'doms_val'. For safty reason, memset all fields of args is better. Fix the following error from valgrind, like: ==30515== 1 errors in context 1 of 3: ==30515== Conditional jump or move depends on uninitialised value(s) ==30515== at 0x85E9402: xdr_array (xdr_array.c:88) ==30515== by 0x4FD8FC9: xdr_remote_connect_get_all_domain_stats_args (remote_protocol.c:6473) ==30515== by 0x4FE72F2: virNetMessageEncodePayload (virnetmessage.c:350) ==30515== by 0x4FDD21C: virNetClientProgramCall (virnetclientprogram.c:326) ==30515== by 0x4FB4D01: callFull.isra.2 (remote_driver.c:6667) ==30515== by 0x4FCBD45: call (remote_driver.c:6689) ==30515== by 0x4FCBD45: remoteConnectGetAllDomainStats (remote_driver.c:7793) ==30515== by 0x4FA0E75: virConnectGetAllDomainStats (libvirt.c:21678) ==30515== by 0x147FD1: cmdDomstats (virsh-domain-monitor.c:2148) ==30515== by 0x13006B: vshCommandRun (virsh.c:1915) ==30515== by 0x12A9E1: main (virsh.c:3699) Signed-off-by: Jincheng Miao <jmiao@redhat.com>
