Subject: scsi-disk: Fix crash if underlying host file or disk returns error

Commit 40dce4ee6 "scsi-disk: fix rerror/werror=ignore" introduced a
bug which causes qemu to crash with the assertion error below if the
host file or disk returns an error:

qemu-system-x86_64: hw/scsi/scsi-bus.c:1374: scsi_req_complete:
  Assertion `req->status == -1' failed.

Kevin Wolf suggested this fix:

< kwolf> Hm, should the final return false; in that patch
           actually be a return true?
  < kwolf> Because I think he didn't intend to change anything
           except BLOCK_ERROR_ACTION_IGNORE
