[PATCH] usb: gadget: f_hid: Add missing error code

[Ethan Tidmore]

Currently in cdev_alloc() error path no error code is assigned.

Assign error code '-ENOMEM'.

Detected by Smatch:
drivers/usb/gadget/function/f_hid.c:1291 hidg_bind()
warn: missing error code 'status'

Fixes: 81ebd43cc0d6d ("usb: gadget: f_hid: don't call cdev_init while cdev in use")
