sh: Make the unaligned trap handler always obey notification levels. 

Presently there are a couple of paths in to the alignment handler, where
only the address error path presently quiets the notificiation messages
based on the configuration settings. We carry over the notification level
tests to the default alignment handler itself incase so that they behave
uniformly.
