bluetooth: hci_intel: Replace GFP_ATOMIC with GFP_KERNEL in inject_cmd_complete()
inject_cmd_complete() is only called by intel_dequeue(), which is never called in atomic context. inject_cmd_complete() 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 also manually check the kernel code before reporting it.
