Don't give method suggestions when method probe fails due to bad implementation of Deref #131024

If we have a bad Deref impl, we used to bail with MethodError::NoMatch, which makes the error reporting code think that there was no applicable method (and thus try to suggest importing something, even if it's in scope).

Suppress this error, which fixes #131003.
