msm ipa: fix the APPS QMI SSR reset sequence

During modem-encryption enable scenario, we saw
RILD in the Android framework always initializes
the modem SSR in the first time reboot and we
saw modem crashed because apps-side didn't
clean internal QMI-flag well and continue the last
time's bootup sequence which causes modem crash.
The fix is to move the flag reset to the
qmi_service_init.
