firewire: fw-sbp2: always enable IRQs before calling command ORB callback
On IOMMU-less noncoherent architectures, orb->callback will memcpy the whole SCSI command buffer for READ-like SCSI commands. It is therefore friendlier to enable IRQs before the call, like before patch "Add ref-counting for sbp2 orbs".
