drivers/net/usb/catc.c: Fix potential deadlock in catc_ctrl_run()

catc_ctrl_run() calls usb_submit_urb() with GFP_KERNEL, while it is called from
catc_ctrl_async() and catc_ctrl_done() with catc->ctrl_lock spinlock held.

The patch replaces GFP_KERNEL with GFP_ATOMIC.

Found by Linux Driver Verification project (linuxtesting.org).
