[PATCH v2] defxx: fix build warning

From: Sudip Mukherjee
Date: Mon Jan 25 2016 - 02:35:33 EST


We are getting many build warnings about:
'bar_start' may be used uninitialized
and
'bar_len' may be used uninitialized

They are not actually uninitialized as dfx_get_bars() will initialize
them properly. But still lets have them initialized just to satisfy the
compiler (gcc 4.8.2).

v2: only the first element is zeroed.
