Problem : getfattr fails and mount point becomes inaccessible while
fetching glusterfs.ancestry.path key value for a gfid from aux-gfid-mount
based mount point.
Analysis : The caller of posix_make_ancestryfromgfid() function i.e.
posix_get_ancestry_non_directory() is sending an incorrect type value as
an argument leading to a crash in posix_make_ancestral_node() (head
dirent pointer is NULL and an attempt to dereference causes seg fault).
For a non directory operation this piece of code should not have been
executed but due to incorrect type value this happened.
Solution : In posix_make_ancestryfromgfid() call type is passed as
logical or of type and POSIX_ANCESTRY_PATH instead of logical or of
POSIX_ANCESTRY_PATH and POSX_ANCESTRY_DENTRY.
