[SCSI] sym53c8xx: free luntbl in sym_hcb_free

This patch frees the luntbl dma area in sym_hcb_free if allocated.
Since the luntbl is part of a larger dma coherent area not freeing the
luntbl kept a 64k dma coherent area previous allocated through
dma_alloc_coherent allocated. This prevented a DLPAR remove IO
operation from completing successfully.
