rec_close.c: Removed usage of munmap() method.

Browse Source 
Note that there is a define MMAP_NOT_AVAILABLE that when NOT
defined results in mmap not being called but munmap is still
called.  A comment was also added to our notes about this.

The MMAP_NOT_AVAILABLE define is inverted on its usage. When it is
defined the mmap method is called. Additionally, it is not used
thoroughly. It is not used in the unmap portion of the source.
