Volume: Hide dialog when motion cancelled, as well as when finished.

Speculative fix for issue where sometimes volume dialog does not
ever dismiss. Logs show that VolumeDialogImpl.dismissH is being called,
and the VolumeDialogImpl dump shows that the dialog thinks it is
not showing. I think that these animations are getting cancelled,
leaving mIsAnimatingDismiss true with no active dismiss animation
running (normally it is reset to false during the animation's end
action). mIsAnimatingDismiss then prevents the creation of another
dismiss animation, leaving the dialog stranded.

Test: existing Volume tests pass, no repro available for bug
