net: usb: lan78xx: Use action-specific label in lan78xx_mac_reset

Rename the generic `done` label to the action-specific `exit_unlock`
label in `lan78xx_mac_reset`. This improves clarity by indicating the
specific cleanup action (mutex unlock) and aligns with best practices
for error handling and cleanup labels.
