bio_add_page() won't fail for resync bio, and the page index for each bio is same, so remove it. More importantly the 'idx' of 'struct resync_pages' is initialized in mempool allocator function, the current way is wrong since mempool is only responsible for allocation, we can't use that for initialization.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
