dmaengine: at_hdmac: fix potential NULL pointer dereference in atc_prep_dma_interleaved
[ Upstream commit 62a277d43d47e74972de44d33bd3763e31992414 ]
_xt_ is being dereferenced before it is null checked, hence there is a
potential null pointer dereference.
Fix this by moving the pointer dereference after _xt_ has been null
checked.
This issue was detected with the help of Coccinelle.
Fixes: 4483320e241c ("dmaengine: Use Pointer xt after NULL check.")
