firewire: core: use kzalloc_flex() to allocate structure with quadlet array
fw_core_handle_request() is now called in process context, so GFP_KERNEL
is available. The fw_request structure has a trailing flexible array
member of quadlets to store packet data. Use kzalloc_flex() to allocate
the structure together with storage for the flexible array member.
