Al Viro 180a9cc3fd make it easier to catch those who try to modify ->d_name ...

Turn d_name into an anon union of const struct qstr d_name with
struct qstr __d_name.  Very few places need to modify it (all
in fs/dcache.c); those are switched to use of ->__d_name.

Note that ->d_name can actually change under you unless you have
the right locking environment; this const just prohibits accidentally
doing stores without being easily spotted.
