ipoib: added an error message when trying to change mtu to 2K-4K

Max mtu defined by IB is 4K, but mcast_mtu is limited to 2K,
so any request to change mtu to a value between 2K-4K didn't
change the mtu, but also didn't show an error message.
An error value (-EINVAL) is now returned and an ipoib_warn
is issued in such cases.
