[PATCH 4/8] usb: gadget: dummy_hcd: fix block comments, blank lines and function braces

[Clint George <clintbgeorge@gmail.com>]

This patch updates dummy_hcd.c to follow the Linux kernel coding style:
- Align block comment asterisks properly.
- Add blank lines after variable declarations where needed.
- Remove unnecessary spaces before semicolons.
- Move opening braces of function definitions to the next line.

These changes improve readability, maintain consistency, and make the code
easier to maintain.
