[svn-r10998] Purpose: Bug fix.

Description:
For the definition of the macro H5T_CONV_Xx_CORE, added a condition branch
(else if (*((ST*)S) == (DT)(D_MAX))) which seems redundant.
It handles a special situation when the source is "float" and assigned the value
of "INT_MAX".  A compiler may do roundup making this value "INT_MAX+1".  However,
when do comparison "if (*((ST*)S) > (DT)(D_MAX))", the compiler may consider them
equal.


Platforms tested: fuss - simple change.
