[PATCH 2 16/24] hpsa: fix event filtering to prevent excessive rescans with old firmware

From: Stephen M. Cameron CTLR_STATE_CHANGE_EVENT and CTLR_STATE_CHANGE_EVENT_REDUNDANT_CNTRL do not require rescans to be initiated. Current firmware filters out these events already, but some out of date firmware doesn't, so the driver needs to filter them out too. Without this chang
