Logan Gunthorpe 717146a2a8 ntb_tool: Postpone memory window initialization for the user ... In order to make the interface closer to the raw NTB API, this commit changes memory windows so they are not initialized on link up. Instead, the 'peer_trans*' debugfs files are introduced. When read, they return information provided by ntb_mw_get_range. When written, they create a buffer and initialize the memory window. The value written is taken as the requested size of the buffer (which is then rounded for alignment). Writing a value of zero frees the buffer and tears down the memory window translation. The 'peer_mw*' file is only created once the memory window translation is setup by the user. Additionally, it was noticed that the read and write functions for the 'peer_mw*' files should have checked for a NULL pointer.
