coresight: etf: Release CLAIM tag after disabling the HW
This patch rectifies the sequence of events in function tmc_etb_disable_hw() by disabling the HW first and then releasing the CLAIM tag. Otherwise we could be corrupting the configuration done by an external agent that would have claimed the device after we have released it.
