ahci: Fix sglist memleak in ahci_dma_rw_buf()
I noticed that in hw/ide/ahci:ahci_dma_rw_buf() we do not free the sglist. Thus, I've added a call to qemu_sglist_destroy() to fix this memory leak. In addition, I've adeed a call in qemu_sglist_destroy() to 0 all of the sglist fields, in case there is some other codepath that tries to free the sglist.
