When performing reset testing, the eq's list for related hwq's was
getting corrupted.  In cases where there is not a 1:1 eq to hwq, the
eq is shared. The eq maintains a list of hwqs utilizing it in case of
cpu offlining and polling. During the reset, the hwqs are being torn
down so they can be recreated. The recreation was getting confused by
seeing a non-null eq assignment on the eq and the eq list became
corrupt.

Correct by clearing the hdwq eq assignment when the hwq is cleaned up.
