Bump the max number of inodes for /dev to 128k

Browse Source 
Follow-up for 7d85383edbab73274dc81cc888d884bb01070bc2.

Apparently the previous limit set on the max number of inodes for /dev was too
small as a system with 4096 LUNs attached can consume up to 95k inodes for
symlinks:

  # /bin/df -i
  Filesystem                 Inodes  IUsed    IFree IUse% Mounted on
  devtmpfs                 49274377  95075 49179302    1% /dev

Hence this patch bumps the limit from 64k to 128k although the new limit is
still pretty arbitrary (that said, not sure if it really makes sense to put
such absolute limit number).
