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.

Fix coccinelle reported warnings:
WARNING: Consider using %pe to print PTR_ERR()

Compile tested only.
