bus: ti-sysc: Fix error handling for sysc_check_active_timer()
We have changed the return type for sysc_check_active_timer() from -EBUSY
to -ENXIO, but the gpt12 system timer fix still checks for -EBUSY. We are
also not returning on other errors like we did earlier as noted by
Pavel Machek <pavel@denx.de>.
Commit 3ff340e24c9d ("bus: ti-sysc: Fix gpt12 system timer issue with
reserved status") should have been updated for commit 65fb73676112
("bus: ti-sysc: suppress err msg for timers used as clockevent/source").
Let's fix the issue by checking for -ENXIO and returning on any other
errors as suggested by Pavel Machek <pavel@denx.de>.
