The dgap_newnode() is useless for creating new node.
So just use kzalloc and set a type in case statement.

The retval in dgap_block_til_ready() is initialized to zero,
and if no error has occurred in this function, the retval has a zero.
So it doesn't need to check "retval" itself.

dgap_param()
The dgap_param() has a paramter which is tty_struct and
use variables in that struct. That variables which are "ch", "bd", "bs"
and "un" do not need to check NULL so these statements are removed.
And also change the parameter of this function because
it is possible to let someone know what paramters
are needed for this function.

The dgap_init_one() needs to handle error properly
if one of functions in dgap_init_one() is failed.
Introduce some functions for handling error in dgap_init_one()
- dgap_tty_unregister() : unregister tty driver
- dgap_free_flipbuf() : free flip buffer
- dgap_release_remap() : release memory region and unmapped memory.
