[svn-r19399] Description:

	Bring r19398 from trunk to 1.8 branch:

	Clean up the internal usage H5I_dec_ref() to eliminate the sequence of
flags that has been creeping in.

Tested on:
       FreeBSD/32 6.3 (duty) in debug mode
       FreeBSD/64 6.3 (liberty) w/C++ & FORTRAN, in debug mode
       Linux/64-ia64 2.6 (cobalt) w/Intel compilers, w/C++ & FORTRAN,
               in production mode
       Linux/64-amd64 2.6 (abe) w/parallel, w/FORTRAN, in debug mode
