Hitoshi Mitake 2c8ffa6bcb etcdserver: correct error log for strict reconfig checking
This commit fixes an error log caused by the strict reconfig checking
option.

Before:
14:21:38 etcd2 | 2015-11-05 14:21:38.870356 E | etcdhttp: got unexpected response error (etcdserver: re-configuration failed due to not enough started members)

After:
log
13:27:33 etcd2 | 2015-11-05 13:27:33.089364 E | etcdhttp: etcdserver: re-configuration failed due to not enough started members

The error is not an unexpected thing therefore the old message is
incorrect.
