Because this only matters for commands that will use the oob_size field
when doing some I/O operation. Both ERASE and RESET commands have no data
cycle, so it makes no sense to haev a non-zero oob_size field.

On the other side, this patch is rather stupid, as oob_size is already
cleared at the beggining of a command sequence. So, I'll either rework
this or drop it entirely.
