[RFC] [PATCHv2 2/3] reiser4: mark final deallocations in wandering log code as deferred.

[Ivan Shapovalov <intelfx100@gmail.com>]

Now there is a clear semantic distinction between deferred and immediate
deallocations. Deferred mode is used to deallocate blocks that were previously
written, immediate mode is used to deallocate "just allocated" blocks in error
paths or if some previously allocated blocks turn out to be unneeded.

This way, we may get rid of discard-related hack in the deallocation routine,
i. e. treating immediate deallocations as deferred (which messes up
block accounting). This is done in the next commit.
