mei: fix max number of open handles
There was internal confusion in wether bus message clinet (0) is counted in or not The bitmap me_clients_map that accomodate was initialized w/o it (255) but later on it the clinet 0 was reserved Thus were able to open only 252 instead of 253 clients Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
