net/mlx5: Fix lockdep assertion on sync reset unload event

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5: Fix lockdep assertion on sync reset unload event

Fix lockdep assertion triggered during sync reset unload event. When the
sync reset flow is initiated using the devlink reload fw_activate
option, the PF already holds the devlink lock while handling unload
event. In this case, delegate sync reset unload event handling back to
the devlink callback process to avoid double-locking and resolve the
lockdep warning.
