[sheepdog] [PATCH] sheep: mute gcc warning of uninitialized devnull_fd

[Liu Yuan]

From: Liu Yuan <tailai.ly at taobao.com>

sheep.c:446:8: warning: ‘devnull_fd’ may be used uninitialized in this function [-Wuninitialized]
sheep.c:395:11: note: ‘devnull_fd’ was declared here

Just init devnull_fd to mute the warning.
