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>.

I double checked but actually both plain 0aa78d17099b ("Merge tag
'scsi-fixes' of
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi") and with this
patch boot fine on my Beagle C2.

Anyway,

OK thanks for testing. I had already pushed out my fixes branch so
I did not want to go back to add the Tested-by. Anyways, a pull
request for this has been sent now.
