[PATCH net v2 0/4] net: mana: Fix probe/remove error path bugs

[Erni Sri Satya Vennela <ernis@linux.microsoft.com>]

Fix four pre-existing bugs in mana_probe()/mana_remove() error handling
that can cause warnings on uninitialized work structs, masked errors,
and resource leaks when early probe steps fail.

Patches 1-2 move work struct initialization (link_change_work and
gf_stats_work) to before any error path that could trigger
mana_remove(), preventing WARN_ON in __flush_work() or debug object
warnings when sync cancellation runs on uninitialized work structs.

Patch 3 prevents add_adev() from overwriting a port probe error,
which could leave the driver in a broken state with NULL ports while
reporting success.

Patch 4 changes 'goto out' to 'break' in mana_remove()'s port loop
so that mana_destroy_eq() is always reached, preventing EQ leaks when
a NULL port is encountered.

Changes in v2:
* Apply the patch in net instead of net-next.
