target/arm_tpiu_swo: Handle errors in pre/post-enable events
Currently, errors in pre/post-enable events are ignored and capturing is
always started, even if necessary device configuration fails. This
behaviour is confusing to users. Also, the TPIU must be disabled before
re-configuration is possible.
Start capturing and enable TPIU only if no errors in pre/post-enable
events occurred.
