[PATCH 2/2] mkfs.ubifs: fix a gcc warning

[Artem Bityutskiy <dedekind1@gmail.com>]

This patch "fixes" the following gcc warning:

mkfs.ubifs/mkfs.ubifs.c: In function ‘main’:
mkfs.ubifs/ubifs.h:420:2: warning: ‘child_cnt’ may be used uninitialized in this function [-Wuninitialized]
mkfs.ubifs/mkfs.ubifs.c:1735:6: note: ‘child_cnt’ was declared here

by initializing the ‘child_cnt’ to zero.
