Kill the cdevsw->d_maxio field.
d_maxio is replaced by the dev->si_iosize_max field which the driver
should be set in all calls to cdevsw->d_open if it has a better
idea than the system wide default.
The field is a generic dev_t field (ie: not disk specific) so that
tapes and other devices can use physio as well.
