A FileSystemProvider may support many views but some of these attributes in these views may not supported on all FileStores. So I think the new added check `haveView == supported` is too strict on non-AIX systems. This PR make this check only on AIX.

test/jdk/java/nio/file/FileStore/Basic.java line 82:

I think we should replace L76-L77 with

if (supported) {
    assertNotNull(Files.getFileAttributeView(file, viewClass));
}

so no need for anything AIX specific here.
