Description of problem:
Check_is_linkfile is failing, entry of readdip does not have dict set.


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. create file
2. rename file till link file is created
3. ls -l on dir
  
Actual results:
2 entries show for same file

Expected results:
1 entry should be shown

Additional info:
This because we were not sending the dict (with linkto key) to server. client protocol needs to propogate the right dict.
Additionally, we needed to allocated dict in readdirp_cbk for each entry before we unserialize the buffer
