xlnx_dp: drop unsupported AUXCommand in xlnx_dp_aux_set_command
In xlnx_dp_aux_set_command, when the command leads to the default
branch, xlxn-dp will abort and then crash.
This patch removes this abort and drops this operation.
Fixes: 58ac482 ("introduce xlnx-dp")
Resolves: https://gitlab.com/qemu-project/qemu/-/issues/411
