John Baldwin 9494dfe1b3 fwcontrol: Allocate full fw_asyreq structures passed to the kernel ... The FW_ASYREQ ioctl accepts a struct fw_asyreq object as its argument, meaning that the kernel always copies in the full structure in sys_ioctl before passing the request down to the driver. However, fwcontrol was allocating smaller objects that contained only the request header and a variable-sized payload. This means that the kernel copy in sys_ioctl was reading off the end of this buffer. On current architectures this happened to be ok, but it is UB. Instead, allocate a full structure.
