Subfiling testing fix and documentation (#2132)
* Fix a sporadic failure in Subfiling VFD tests
* Subfiling VFD - add note to H5Pget_fapl_subfiling documentation
Adds note about how H5Pget_fapl_subfiling only returns the original
settings on a FAPL and those settings could have been modified by the
Subfiling VFD's environment variables
