mei: use mei_cl_is_connected consistently
Replace open coded check for cl->state !=/== MEI_FILE_CONNECTED with mei_cl_is_connected function. Note that cl->state != MEI_FILE_CONNECTED is not the same as cl->state == MEI_FILE_DISCONNECTED Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
