N_TTY_BUF_SIZE -- as the name suggests -- is the N_TTY's buffer size.
There is no reason to couple that to caif's tty->receive_room. Use 4096
directly -- even though, it should be some sort of "SKB_MAX_ALLOC" or
alike. But definitely not N_TTY_BUF_SIZE.

N_TTY_BUF_SIZE is private and will be moved to n_tty.c later.
