Dave Kleikamp aca0fa34bd jfs: don't allow os2 xattr namespace overlap with others 
It's currently possible to bypass xattr namespace access rules by
prefixing valid xattr names with "os2.", since the os2 namespace stores
extended attributes in a legacy format with no prefix.

This patch adds checking to deny access to any valid namespace prefix
following "os2.".
