msm: ipa: send the endp_desc QMI for low_lat only on non-auto mode 



There is no low_lat use case on auto mode, so the ep mapping is
not defined.
Add sanity check to not sent endp_desc QMI for ep which is not
defined.
Add check to make sure send endp_desc specific to low lat only
for mhi non-auto case.
