[PATCH v2 1/3] qemu: agent: fix uninitialized var case in qemuAgentGetFSInfo

[Nikolay Shirokovskiy <nshirokovskiy@xxxxxxxxxxxxx>]

In case of 0 filesystems *info is not set while according
to virDomainGetFSInfo contract user should call free on it even
in case of 0 filesystems. Thus we need to properly set
it. NULL will be enough as free eats NULLs ok.
