Subject: [PATCH 55/60] staging: lustre: obd: move s3 in lmd_parse to inner loop

Building the lustre client with W=1 reports the following
error:

obdclass/obd_mount.c: In function lmd_parse:
obdclass/obd_mount.c:880: warning: variable set but not used

The solution is to move s3 to the inner loop
where it is only used.
