makedev(9): drop an additional note about cdevpriv dtors

These were previously somewhat safe to call destroy_dev(9), but will now
also cause a deadlock in the same fashion that d_close doing so would
previously. Amend the note to point it out, in case it's useful for
someone.

make_dev.9: Fix mda_cr typo + polish

The make_dev_args_init structure example said mda_cred, however the
correct form is mda_cr according to the reporter and my git grep.

make_dev.9: Fix mda_cr typo + polish

The make_dev_args_init structure example said mda_cred, however the
correct form is mda_cr according to the reporter and my git grep.
A new document description has been contributed by jhb. While here,
fix grammar and trivial typos (spacing, colons before examples,
trailing delimiter) and spdx.

Provide yet another KPI for cdev creation, make_dev_s(9).

Immediate problem fixed by the new KPI is the long-standing race
between device creation and assignments to cdev->si_drv1 and
cdev->si_drv2, which allows the window where cdevsw methods might be
called with si_drv1,2 fields not yet set. Devices typically checked
for NULL and returned spurious errors to usermode, and often left some
methods unchecked.

The new function interface is designed to be extensible, which should
allow to add more features to make_dev_s(9) without inventing yet
another name for function to create devices, while maintaining KPI and
even KBI backward-compatibility.
