broadband-modem-qmi: avoid NULL success return in firmware_load_current

Browse Source 
Instead of assuming that NULL is a valid return, make sure we return
an error instead.

This also makes it sure that if the GTask gets cancelled, the result
we set is always a valid GObject, so that the g_object_unref passed as
GDestroyNotify can be safely called always. Not a big deal anyway, as
the GTask cannot be currently cancelled.
