zram_reset_device() waits for ongoing writepage pages to be completed by zram->refcount logic. However, it's pointless because before the reset, we prevent further opening of zram by zram->claim and flush all of pending IO by fsync_bdev so there should be no pending IO at the zram_reset_device(). So let's remove that code which is even broken due to the lack of wake_up elsewhere.

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.
