Even if pm_runtime_get*() fails, you still need to decrement the usage counter. pm_runtime_put*() is one way of achieving so.

dwc3_probe() does pm_runtime_put_sync() in its err1 handling when pm_runtime_get_sync() fails. Move the pm_runtime_put_sync() under err2 instead as it is used in error paths after pm_runtime_get_sync() succeeds.
