MAINTAINERS: make me a reviewer of USB/IP

I think I am familiar enough with USB/IP and is adequate as a reviewer.

Every time there is some patch/bug, I wish I can get pinged
and I will feedback on that.

I had some contributions to USBIP and some support for it.

Contribution:
Commit 17af793 ("docs: usbip: Fix major fields and
    descriptions in protocol")
Commit b737eec ("usbip: tools: add options and examples
    in man page related to device mode")
Commit a58977b ("usbip: tools: add usage of device mode in
    usbip_list.c")

Support:
Commit 8f36b3b ("usbip: add USBIP_URB_* URB transfer flags")
Bug report: https://lore.kernel.org/lkml/ZBHxfUX60EyCMw5l@Sun/

I also have implemented a userspace usbip server in
https://github.com/canokeys/canokey-usbip
and maintain a list of usbip implementations
https://github.com/usbip/implementations
