Josh Boyer ea36ae0910 HID: lenovo: Don't use stack variables for DMA buffers 
The lenovo_send_cmd_cptkbd function uses a stack variable to submit
commands via hid_hw_raw_request.  Eventually this gets to the
usb_hcd_map_urb_for_dma function, which causes a warning to be thrown
if the CONFIG_DMA_API_DEBUG option is enabled.

Fix this by allocating a temporary buffer instead.

[jkosina@suse.cz: no need to NULL-initialize buf, spotted by Benjamin]
