[PATCH] bluetooth: bfusb: Replace GFP_ATOMIC with GFP_KERNEL in bfusb_send_frame()

bfusb_send_frame() is only set to hdev->send, and hdev->send() is never called in atomic context. bfusb_send_frame() calls bt_skb_alloc() with GFP_ATOMIC, which is not necessary. GFP_ATOMIC can be replaced with GFP_KERNEL. This is found by a static analysis tool named DCNS written by myself. I
