[PATCH net-next 1/4] net: mana: Init link_change_work before potential error paths in probe

[Erni Sri Satya Vennela]

Move INIT_WORK(link_change_work) to right after the mana_context
allocation, before any error path that could reach mana_remove().

Previously, if mana_create_eq() or mana_query_device_cfg() failed,
mana_probe() would jump to the error path which calls mana_remove().
mana_remove() unconditionally calls disable_work_sync(link_change_work),
but the work struct had not been initialized yet. This can trigger
CONFIG_DEBUG_OBJECTS_WORK enabled.

Fixes: 54133f9b4b53 ("net: mana: Support HW link state events")
