me_daq: don't access *data when insn->n == 0

Due to recent change to do_insnlist_ioctl() and do_insn_ioctl(), the
'data' pointer will be NULL when insn->n == 0.  Do not access *data
in this case.

Also for INSN_WRITE on the AO subdevice, write the nth data value in the
loop instead of the 0th data value.
