n_tty: simplify and sanitize zero_buffer()

Browse source

* Make 'tty' parameter const as we only look at tty flags here.
* Make 'size' parameter of size_t type as everyone passes that and
  memset() (the consumer) expects size_t too. So be consistent.
* Remove redundant local variables, place the content directly to the
  'if'.
* Use 0 instead of 0x00 in memset(). The former is more obvious.

No functional changes expected.
