Gustavo A. R. Silva 05fc2b8ba0 dmaengine: at_hdmac: fix potential NULL pointer dereference in atc_prep_dma_interleaved ...

[ Upstream commit 62a277d43d ]

_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: 4483320e24 ("dmaengine: Use Pointer xt after NULL check.")
