Subject: [PATCH 07/12] staging/lustre/mgc: inline mgc_cancel()

From: "John L. Hammond" <john.hammond@...el.com>

The function mgc_cancel() is never invoked as an OBD device method and
is only called directly from mgc_process_log() so remove it.

Signed-off-by: John L. Hammond <john.hammond@...el.com>
