qemu: Fix migration without parameters

The virTypedParamsFilter function doesn't mind params == NULL if nparams
is zero. And there's no need to check for params == NULL && nparams > 0
because this is checked higher in the stack.

In fact all the virCheckNonNull* checks in virTypedParamsFilter are
useless.
