net: ethernet: xilinx: Drop kernel doc comment about return value

During review of the patch that became 2e0ec0af ("net: ethernet:
xilinx: Convert to platform remove callback returning void") in
net-next, Radhey Shyam Pandey pointed out that the change makes the
documentation about the return value obsolete. The patch was applied
without addressing this feedback, so here comes a fix in a separate
patch.
