bsp/atsam: Fix XDMAD status
In "bsp/atsam: Simplify XDMAD_Handler()" (5f813694f68cee) the interrupt
callback has been made unconditional. That allowed to avoid some special
deadlock situations in error cases. But it removed part of the XDMAD
status handling.
This patch adds the ability to update the XDMAD status from the
callback if that is necessary for the driver.
Fixes #4173
