Adds a comment and a check to ntb_mw_get_align() so that it always fails if the function is called before the link is up. Also adds a comment to ntb_mw_count() to note that it may return 0 if it is called before the link is up. This is to prevent accidental mis-use in clients that are testing on hardware that this doesn't matter for.

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.
