4.16-stable review patch.  If anyone has any objections, please let me know.

------------------

From: oulijun <oulijun@xxxxxxxxxx>

[ Upstream commit 215a8c09e5e2aa6ae1fbcef87f8f27d65d5d1ca4 ]

During init hem table, type should be used instead of
table->type which is finally initializaed with type.
