Revert "ihandle: Ensure FDH_REALLYCLOSE really closes"

This reverts commit a50f4c8d802c7b1c258a9cbe388dfab50425596b.

The only difference between FDH_CLOSE and FDH_REALLYCLOSE has to do
with ihandle cache behavior. FDH_REALLYCLOSE just indicates that the
reference we are closing is not likely to be used by other code, and
should be kicked out of the cache immediately (thus closing the file
descriptor). So, if there is another reference to that FdHandle_t, and
it issues an FDH_CLOSE, it thinks that the reference is likely to be
used again soon, and so the handle should not be kicked out of the
cache. Thus, the behavior before a50f4c8d was already correct.
