Close the file descriptor in ApplyLogicalMappingFile

Browse Source 
The function was forgetting to close the file descriptor, resulting
in failures like this:

  ERROR:  53000: exceeded maxAllocatedDescs (492) while trying to open
  file "pg_logical/mappings/map-4000-4eb-1_60DE1E08-5376b5-537c6b"
  LOCATION:  OpenTransientFile, fd.c:2161

Simply close the file at the end, and backpatch to 9.4 (where logical
decoding was introduced). While at it, fix a nearby typo.
