driver core: fix documentation of request_firmware_nowait
request_firmware_nowait declares it can be called in non-sleep contexts, but kthead_run called by request_firmware_nowait may sleep. So fix its documentation and comment to make callers clear about it. Signed-off-by: Ming Lei <tom.leiming@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
