[PATCH] usb: gadget: uvc: clean up code style for checkpatch compliance

[Darshan Rathod <darshanrathod475@gmail.com>]

This patch fixes a few coding style issues:
- Avoids assignments in if conditions
- Corrects parameter indentation and alignment
- Trims inconsistent spacing

All updates conform to kernel coding standards and improve maintainability.
