Never inline when no_sanitize attributes differ

The inliner looks if a sanitizer is enabled before considering
`no_sanitize` attribute as possible source of incompatibility.

The MIR inlining could happen in a crate with sanitizer disabled, but
code generation in a crate with sanitizer enabled, thus the attribute
would be incorrectly ignored.

To avoid the issue never inline functions with different `no_sanitize`
attributes.
