RFR: 8315034 : File.mkdirs() occasionally fails to create folders on Windows shared folder

[Weibing Xiao]

File.mkdirs() occasionally fails to create folders on Windows shared folders. It turned out that Windows API FindFirstFileW created the error ERROR_NO_MORE_FILES. In some of the cases with a valid file path, this error still returns this error code, which supposedly should not.

Adding this error code into the method of lastErrorReportable in the native code will be handled by JDK.

To test the fix, it needs to run three Java processes to create the folders on a remote file server.
