svn commit: r327699 - head/sys/sys

[Pedro F. Giffuni]

Author: pfg
Date: Mon Jan  8 15:54:29 2018
New Revision: 327699
URL: https://svnweb.freebsd.org/changeset/base/327699

Log:
  Revert r327697:
  malloc(9): drop the __result_use_check attribute for the kernel allocator.
  
  My bad: __result_use_check just checks the for the general and we always
  want to make sure allocated memory is used, not only checked for nullness.
  
  Add it to reallocf since that was missing.
