Subject: scsi: aacraid: Fix INTx/MSI-x issue with older controllers
From: Dave Carroll <david.carroll@xxxxxxxxxxxxx>
commit 8af8e1c22f9994bb1849c01d66c24fe23f9bc9a0 upstream.
commit 78cbccd3bd68 ("aacraid: Fix for KDUMP driver hang")
caused a problem on older controllers which do not support MSI-x (namely
ASR3405,ASR3805). This patch conditionalizes the previous patch to
controllers which support MSI-x
