dma: Fix error_callback enable/disable confusion

Browse source 
Previously the logic was inverted for error_callback_en where 0 was
enablement and 1 was disable. This was likely done so that the default,
sensibly so, was to enable the error callback if possible. A variety of
in tree users had confused the enable/disable value.

Change the name of the flag to error_callback_dis where the default
remains 0 (do not disable the callback!) and correct in tree uses of the
flag where it seemed incorrect.
