IterMut violates Stacked Borrows by invalidating internal pointer

Affected versions of this crate contain a soundness issue in the IterMut
iterator implementation. The IterMut::next and IterMut::next_back
methods temporarily create an exclusive reference to the key when
dereferencing the internal node pointer.

This invalidates the shared pointer held by the internal HashMap,
violating Stacked Borrows rules.
