[PATCH 2/3] usb: misc: Use %pe to print error pointers

[Subasri S]

Use the %pe format specifier instead of %ld with PTR_ERR() for printing
error pointers in various drivers across usb subsystem.
This prints symbolic error names (e.g.-ENOMEM) instead of
errno numbers (e.g. -12), making error logs more readable.

This patch fixes coccinelle reported warnings:
./misc/usb3503.c:206:5-12: WARNING: Consider using %pe to print PTR_ERR()
./atm/usbatm.c:983:14-21: WARNING: Consider using %pe to print PTR_ERR()
./core/hub.c:5675:6-13: WARNING: Consider using %pe to print PTR_ERR()
./gadget/function/u_serial.c:1315:24-31: WARNING: Consider using %pe to print PTR_ERR()
./dwc2/pci.c:72:3-10: WARNING: Consider using %pe to print PTR_ERR()

Compile tested only.
