USB: Set power supply online status to false after cable disconnect

During bootup, power supply online status is set to true in
qpnp_charger_probe() as soon as usb cable insert is detected by
PMIC without waiting for notification from USB driver.
Later when usb cable is disconnected before charger detection
mechanism starts, online status is not set to false by USB.
As part of cable disconnect, USB checks in msm_otg_notify_charger()
whether the cur_power is same as requested mA, if both are same
then USB does not call power_supply_set_online() to set it to false.

Fix the issue by setting power supply online status to false for
the scenario when usb cable is disconected during bootup before
charger detection mechanism is completed.

ASoC: msm: q6: update render flag to NON_DMA for handling underrun

In scenarios where the driver is in underrun state, restart
mechanism triggers when the render flag is in NON_DMA mode. The
compressed driver which is opened in mmap mode runs into underrun
scenarios when the valid buffer length is smaller than the
buffering in the DSP. Update render flag accordingly so that the
restart is trigger when driver is in underrun state.
