The param needs to be virTypedParamsFree()'d in cmdSchedInfoUpdateOne().

[You used git send-email incorrectly - when it asks what to use as
in-reply-to, you should hit 'enter' with blank text to create a new
thread, rather than attempting to answer 'y' which threads it to any
other thread that also used the incorrect 'y' as a message id. Newer
git prevents the use of invalid message ids - so another solution is to
upgrade your git.]

Unfortunately, your patch is incorrect. When applying it, and
re-running 'make check', I get a failure:

Looking more at the code, param is only ever set to &(src_params[i]),
which means that it is NOT allocated locally, and therefore must NOT be
freed locally.

The test failure is because you are freeing an incorrect pointer.
Please fix and resubmit.
Even better, first prove that there is a memory leak (do you have a
valgrind trace to back up your claim? What command line can be used to
demonstrate the leak?). I didn't audit whether there is a leak
somewhere else, but just on inspection, if there IS a leak, it is NOT in
cmdSchedInfoUpdateOne(), but elsewhere.
