drm/i915/guc: Replace zero-length arrays with flexible-array members
Zero-length arrays are deprecated[1] and we are moving towards
adopting C99 flexible-array members, instead. So, replace zero-length
arrays in a couple of structures (three, actually) with flex-array
members.
This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
routines on memcpy() and help us make progress towards globally
enabling -fstrict-flex-arrays=3 [2].
