NTB: Add check and comment for link up to mw_count() and mw_get_align()
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. Signed-off-by:Logan Gunthorpe <logang@deltatee.com> Acked-by:
