usb: gsi: Enable host remote-wakeup capability for GPS function 



Currently the driver is not setting is_suspended flag for
GPS function which is leading to remote wakeup failure for
host. Also clear rwake_inprogress flag in gsi_resume before
bailing out early for GPS function so that driver can
successfully do remote-wakeup for the functions that support
this feature.
