staging: lustre: lov: add cl_object_layout_get()
Add cl_object_layout_get() to return the layout and generation of an
object. Replace some direct accesses to object LSM with calls to this
function.
In ll_getxattr() factor out the LOV xattr specific handling into a new
function ll_getxattr_lov() which calls cl_object_layout_get(). In
ll_listxattr() call ll_getxattr_lov() to determine if a lustre.lov
xattr should be emitted. Add lov_lsm_pack() to generate LOV xattrs
from a LSM.
Remove the unused functions ccc_inode_lsm_{get,put}() and
lov_lsm_get().
