scsi: qedi: Fix a possible memory leak in qedi_alloc_and_init_sb()

Hook "qedi_ops->common->sb_init = qed_sb_init" does not release the DMA
memory sb_virt when it fails. Add dma_free_coherent() to free it. This
is the same way as qedr_alloc_mem_sb() and qede_alloc_mem_sb().

Fixes: ace7f46b ("scsi: qedi: Add QLogic FastLinQ offload iSCSI driver framework.")
