The cdevpriv_dtr_t typedef was not able to be used in a function prototype

like the various d_*_t typedefs since it declared a function pointer rather
than a function.  Add a new d_priv_dtor_t typedef that declares the function
and can be used as a function prototype.  The previous typedef wasn't
useful outside of the cdevpriv implementation, so retire it.

The name d_priv_dtor_t was chosen to be more consistent with cdev methods
since it is commonly used in place of d_close_t even though it is not a
direct pointer in struct cdevsw.
