This patch set is aimed at removing checkpatch issues from files in
lustre/lustre/mdc.

Is it ok if I just fix those in this set and post another patch set
to take care of other issues identified in review?

- removing typedef for ldlm_policy_data_t will touch many other
files/dirs which were not initially targeted for this patch set.
- There can be a separate patch to remove __u64.
