LU-12151 osd-ldiskfs: pass owner down rather than transfer it

Currently, for object creation, initially uid/gid set as 0,
and then osd_quota_trasfer() is called to correct space accounting
for non-root users, function call is like:

|->osd_create
  |->osd_create_type_f
     |->osd_mkreg
        |->ldiskfs_create_inode
           |->ext4_new_inode() ->owner as NULL, create 0 as uid/gid
      |->osd_attr_init
         |->osd_quota_transfer  ->which will change uid/gid again for above.

This is inefficient since osd_quota_transfer() is a more
heavy operations, we could just pass downer owner(uid,gid),
project quota will inherit from its' parents automatically
when creating inode.

Some distros ext4 still did not support passing @owner down,
that is (rhel6,sles11) we just added extra @owner arg in
ldiskfs_create_inode() to make build system happy, and we
could add similar support to older kernel if that is really needed.

Command:
 $ salloc -N 32 --ntasks-per-node=24 mpirun -np 768 mdtest -n 2000
	-F -u -d <mnt>

Without Patch:
Users		Speed
root		175741.938 ops/sec
non-root 	108631.673 ops/sec

Patched:
Users		Speed
root		184775.286 ops/sec
non-root 	185218.466 ops/sec

Patch improved ~80% for non-root users and we reached
same speed for both root and non-root users.
