Lee Jones eeed948c1d usb: dwc2: gadget: Avoid pointless read of EP control register 
Commit ec1f9d9f01 ("usb: dwc2: gadget: parity fix in isochronous mode") moved
these checks to dwc2_hsotg_change_ep_iso_parity() back in 2015.  The assigned
value hasn't been read back since.  Let's remove the unnecessary H/W read.

Fixes the following W=1 warning:

 drivers/usb/dwc2/gadget.c: In function ‘dwc2_hsotg_epint’:
 drivers/usb/dwc2/gadget.c:2981:6: warning: variable ‘ctrl’ set but not used [-Wunused-but-set-variable]
 2981 | u32 ctrl;
