[U-Boot] [PATCH] fix: tools: kwbimage.c: Initialize headersz to suppress warning

[Albert ARIBAUD]

Hello Lukasz,

Thank you and Guillaume for the indications. So gcc 4.7.2 and 4.8.1
should exhibit the problem.

Apparently, 4.7.4 and 4.8.3 don't. :(

/me goes and fetches a 4.8.1 somewhere.

Amicalement,
