[PATCH] mlxsw: core: Fix an error handling path in 'mlxsw_core_bus_device_register()'

[Christophe JAILLET]

Resources are not freed in the reverse order of the allocation.
Labels are also mixed-up.

Fix it and reorder code and labels in the error handling path of
'mlxsw_core_bus_device_register()'

Please review carefully. This patch is proposed because it triggers one of
my coccinelle scripts. I'm not 100% sure if correct.

The script tries to spot wrongly ordered error handling path. It is:
@@
identifier l1, l2;
@@

   if (...) {
      ...
*     goto l1;
   }
   ...
   if (...) {
      ...
*     goto l2;
   }
   ...
*l1:
   ...
*l2:
   ...
