[patch] ide: missing break statement in set_timings_mdma()

[Dan Carpenter]

There was clearly supposed to be a break statement here.  Currently we
use the k2 ata timings instead of sh ata ones we intended.  Probably no
one has this hardware anymore so it likely doesn't make a difference
beyond the static checker warning.
