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.
