In the DMA memory resource get failed case, the error is not
set and 0 will be returned. Fix it by reove redundant check
since devm_ioremap_resource() will handle it.

Fixes: 28ef9ebdb64c ("net: axienet: make use of axistream-connected attribute optional")

I meant "Applied with the commit message typo fixed." :-)
