xfs: constify xfs_name_dotdot
The symbol xfs_name_dotdot is a global variable that the xfs codebase
uses here and there to look up directory dotdot entries. Currently it's
a non-const variable, which means that it's a mutable global variable.
So far nobody's abused this to cause problems, but let's use the
compiler to enforce that.
