[ Upstream commit e9d0e7511fda92a6511904996dd0aa57b6d7687a ]

This function is type bool, and it's supposed to return true on success.
Unfortunately, this path takes negative error codes and casts them to
bool (true) so it's treated as success instead of failure.

Fixes: 91c0c12080d0 ("thunderbolt: Add support for lane bonding")
