USB: OTG: msm: Clear in_lpm flag before enabling the IRQ in resume
The current code is clearing in_lpm flag after enabling the IRQ.
If IRQ comes immediately before in_lpm flag is set, it thinks that
hardware is in low power mode and disables the IRQ. Fix this by
clearing in_lpm flag before enabling the IRQ.
