[PATCH net 3/3] mlxsw: spectrum: Add missing DCB rollback in error path

[Ido Schimmel]

We correctly execute mlxsw_sp_port_dcb_fini() when port is removed, but
I missed its rollback in the error path of port creation, so add it.

Fixes: f00817df2b42 ("mlxsw: spectrum: Introduce support for Data Center 
Bridging (DCB)")
