Xiaomeng Tong 358a3846f6 dma: at_xdmac: fix a missing check on list iterator 
commit 206680c4e46b62fd8909385e0874a36952595b85 upstream.

The bug is here:
	__func__, desc, &desc->tx_dma_desc.phys, ret, cookie, residue);

The list iterator 'desc' will point to a bogus position containing
HEAD if the list is empty or no element is found. To avoid dev_dbg()
prints a invalid address, use a new variable 'iter' as the list
iterator, while use the origin variable 'desc' as a dedicated
pointer to point to the found element.
