Subject: [PATCH 03/12] staging/lustre/osc: remove obsolete llog handling code

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

In osc_request.c there is no reason to handle any llog contexts since
they are never setup. Remove the functions unused function
osc_llog_init() and the obsolete function osc_llog_finish(). Remove
the llog cleanup code in osc_disconnect() and osc_precleanup().
