 Description   

mds-survey print out such messages:

[54673.930490] LustreError: 8214:0:(echo_client.c:1663:echo_md_lookup()) lookup MDT0000-tests: rc = -2
[54673.932912] LustreError: 8214:0:(echo_client.c:1862:echo_md_destroy_internal()) Can't find child MDT0000-tests: rc = -2
[54673.937746] LustreError: 8219:0:(lod_object.c:1452:lod_verify_md_striping()) lustre-MDT0000-mdtlov: invalid lmv_user_md: magic = bd30bd0, stripe_offset = 0, stripe_count = 0: rc = -22

These noises shouldn't be printed, and there are two types:
1. lookup/unlink shouldn't print error when target doesn't exist.
2. echo_md_create_internal should pass in correct lmv_user_md magic when creating directory.
