bonding: Return nothing for not applicable values
From: Wagner Ferenc <wferi@niif.hu>
The previous code returned '\n' (that is, a single empty line)
from most files, with one exception (xmit_hash_policy), where
it returned 'NA\n'. This patch consolidates each file to return
nothing at all if not applicable, not even a '\n'.
I find this behaviour more usual, more useful, more efficient
and shorter to code from both sides.
