[PATCH 1/7] librdmacm/rspreload: Call real.close in fd_close

The index into the preload lookup table is obtained by opening
/dev/null and use the returned value.  When closing the file,
use the real close call and not the preload close call.  This
is a minor optimization, but clarifies the expected operation.
