Description

Fix in RANGER-1181 added fallback to native authorizer for each level - parent/ancestor/self/subAccess. In the newly added fallback cases, FsAction.NONE was sent to the default authorizer - which caused the default authorizer to traverse the entire sub-tree to validate subAccess. This can cause performance issues, if the subtree has large number of files/directories.

Calls to default authorizer should send null, instead of FsAction.NONE - this will eliminate the unnecessary subtree traversal.
