macio: fix NULL pointer dereference when issuing IDE trim
Commit ef0e64a9 "ide: pass IDEState to trim AIO callback" changed the IDE trim callback from using a BlockBackend to an IDEState but forgot to update the dma_blk_io() call in hw/ide/macio.c accordingly. Without this fix qemu-system-ppc segfaults when issuing an IDE trim command on any of the PPC Mac machines (easily triggered by running the Debian installer).
