eal: avoid error for non-existent default PMD path

Browse Source 
If the default location for the PMD .so files does not exist, it should
not be treated as a fatal error condition like an incorrect path on the
command line. Therefore check that the path exists and is a directory
before adding it to the list of paths to check for PMDs.
