[PATCH] ohci1394, sbp2: fix "scsi_add_device failed" with PL-3507 based devices
Re-enable posted writes for status FIFO. Besides bringing back a very minor bandwidth tweak from Linux 2.6.15.x and older, this also fixes an interoperability regression since 2.6.16: http://bugzilla.kernel.org/show_bug.cgi?id=6356 (sbp2: scsi_add_device failed. IEEE1394 HD is not working anymore.)
