common/rc: catch updated suspicious RCU usage message in _check_dmesg()

In the v4.11 kernel, the suspicious RCU usage message uses the word
"ERR" rather than "INFO".  Update _check_dmesg to accept both
versions.

[eguan: see kernel commit 4d4f88fa235f ("lockdep: Make RCU
suspicious-access splats use pr_err")]
