LU-16954 llite: do not set SB_I_CGROUPWB on super block

On clients with a more recent kernel e.g. ubuntu2204,
this makes the mount fails sometimes with
sysfs: cannot create duplicate filename '/devices/virtual/bdi/lustre-ffff8dd549f3d000'

Fixes: f5a75ea44d ("LU-16697 llite: Set BDI_CAP_* flags for lustre")
Test-Parameters: clientdistro=ubuntu2204 testlist=sanity,conf-sanity
