Jiri Pirko 4340f42f20 mlxsw: spectrum: Fix use-after-free of split/unsplit/type_set in case reload fails 
In case of reload fail, the mlxsw_sp->ports contains a pointer to a
freed memory (either by reload_down() or reload_up() error path).
Fix this by initializing the pointer to NULL and checking it before
dereferencing in split/unsplit/type_set callpaths.

Fixes: 24cc68ad6c ("mlxsw: core: Add support for reload")
