dma40: unconfigure on allocation failure
Set the channel configured state to false on an allocation
failure so that if the channel is later attempted to be
allocated as a memcpy channel (i.e. no filter function to
reconfigure it), it is correctly configured as memcpy
instead of incorrectly using a left-over slave configuration.
