The latter handles only NULL pointers, thus a nasty crash will occur. Drop the unnecessary fail label and the associated checks - both err and fb will be set at this stage.

However, this means that put_pages() now needs to check that msm_gem_object::sgt is not null before trying to clean it up, and this check was only applied to part of the cleanup code. Move it all into the conditional block. (Strictly speaking we don't need to make the kfree() conditional, but since we can't avoid checking for null ourselves we may as well do so.)
