svn commit: r342094 - head/sys/mips/include

[Warner Losh]

Author: imp
Date: Fri Dec 14 19:14:51 2018
New Revision: 342094
URL: https://svnweb.freebsd.org/changeset/base/342094

Log:
  atomic_fcmpset* return int, not the type of *.
  
  fcmpset returns true/false as a int, so make the return types and
  variables match the int to be consistent with other arch.
