Another fix for hlist_for_each_entry_safe.

Although the previous patch does fix hlist_for_each_entry_safe for the
common case, it doesn't work correctly when deleting the current
node.  To fix this, introduce two macros - hlist_for_each_entry_safe
for iterating through a list that can be modified, and
hlist_for_each_entry_pprev for those users that only need access to
the "pprev" pointer.
