Fix an ICE caused by type mismatch errors being ignored
This PR fixes #87771. It turns out that the check on `compiler/rustc_typeck/src/check/demand.rs:148` leads to the ICE. I removed it because the early return in [`check_expr_assign`](dec7fc3ced/compiler/rustc_typeck/src/check/expr.rs (L928)
) already prevents unnecessary error messages from the call to `check_expr_coercable_to_type`.
