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.
