William Wu ea9afa6584 usb: gadget: udc: core: fix possible NULL pointer dereference 
This patch fixes the following panic when use uvc function and
do reboot during uvc preview.

Unable to handle kernel NULL pointer dereference at virtual address 000001fd
pgd = 85dd55c1
[000001fd] *pgd=00000000
Internal error: Oops: 17 [#1] PREEMPT SMP ARM
Modules linked in: galcore(O)
CPU: 0 PID: 716 Comm: xc:RkAiqCoreThr Tainted: G        W  O      4.19.111 #18
Hardware name: Generic DT based system
PC is at usb_gadget_deactivate+0x0/0x6c
LR is at usb_function_deactivate+0x54/0x74

It's because that do reboot operation will call configfs_composite_unbind()
to set cdev->gadget to NULL.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
