[PATCH 1/7] qemuagenttest: Don't leak virTypedParameter on failure

[Michal Privoznik]

There are two functions (testQemuAgentOSInfo() and
testQemuAgentTimezone()) which call virTypedParamsFree() only in
successful paths. If an error is met then those parameters would
be leaked. Fix this by placing the virTypedParamsFree() calls on
better place.
