svn commit: r268507 - head/sys/kern

[Mateusz Guzik]

Author: mjg

New Revision: 268507
URL: http://svnweb.freebsd.org/changeset/base/268507

Log:
  Don't zero fd_nfiles during fdp destruction.
  
  Code trying to take a look has to check fd_refcnt and it is 0 by that time.
  
  This is a follow up to r268505, without this the code would leak memory for
  tables bigger than the default.
