Fixed H5Ovisit2() change of behavior between 1.10.11 and v1.14.4.3 (H…

…DFGroup#5022)

H5O__visit() uses the object information to be returned to the
application, so when the application did not request for certain
information, they were not available to H5O__visit.  This lack of
information caused incorrect behavior down the road.

We now call H5O_get_info again providing H5O_INFO_BASIC for "fields",
so we can obtain correct object information for H5O__visit to use.

Fixes HDFGroup#4941

+
+      h5dump produced a segfault on a mal-formed file because a B-tree node
+      level was corrupted.
+
+      An internal function was modified to help detecting when a decoded B-tree
+      node level has an unexpected value and an error will be produced.

+      H5Ovisit2 visited only the root group and not all the nested groups.
+
+      This behavior occurred when the fields are not H5O_INFO_BASIC or
+      H5O_INFO_ALL because an internal function did not obtain the basic
