USB: msm_otg: Abort suspend while host mode is activated

ID ground interrupt processing and system suspend can run in parallel.
When Id is grounded, USB is brought out of low power mode(LPM) and state
machine work is run to activate host mode.  While waiting for the VBUS
valid event, device suspend callback is executed from system suspend
context.  The current code put USB in LPM, without activating host mode
completely.  Abort suspend when A_BUS_REQ is asserted which indicate
that host mode is active.
