[SCSI] fusion: fix for BZ 8426 - massive slowdown on SCSI CD/DVD drive

Patch for: http://bugzilla.kernel.org/show_bug.cgi?id=8426

A recent code cleanup that moved code from mptscsih to mptspi
inadvertently change the order some code was called.  This caused
a massive slowdown (of 150x to 300x) on the CD/DVD drive on the
high-end HP Integrity servers.
