usb: f_gsi: Don't set remote_wakeup_allowed to true by default

Currently USB remote wakeup functionality is not fully supported.
Hence set remote_wakeup_allowed to false instead of setting true.
This helps to disconnect USB IPA GSI channel instead of suspending
on getting suspend interrupt when USB is enumerated into high speed.
It prevents getting any unwanted remote wakeup from IPA which is
racing against USB LPM functionality causing unclock USB controller
register access while handling remote wakeup.
