devlink: Fix phys_port_name of virtual port and merge error

Merge commit cited in fixes tag was incorrect. Due to it phys_port_name
of the virtual port resulted in incorrect name.

Also the phys_port_name of the physical port was written twice due to
the merge error.

Fix it by removing the old code and inserting back the misplaced code.
