macio: fix NULL pointer dereference when issuing IDE trim
Commit ef0e64a983 "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).
