net: axienet: Fix error return code in axienet_probe()

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

Fixes: 28ef9ebdb6 ("net: axienet: make use of axistream-connected attribute optional")
