[PATCH v3 13/42] hpsa: print accurate SSD Smart Path Enabled status

From: Robert Elliott <elliott@hp.com>

offload_enabled changes are deferred until after the
added/updated prints occur, so the values are incorrect.

defer printing SSD Smart Path Enabled status information until the
information is correct
