sfc: Fix MCDI command size for filter operations
[ Upstream commit bb53f4d4f5116d3dae76bb12fb16bc73771f958a ] The 8000 series adapters uses catch-all filters for encapsulated traffic to support filtering VXLAN, NVGRE and GENEVE traffic. This new filter functionality requires a longer MCDI command. This patch increases the size of buffers on stack that were missed, which fixes a kernel panic from the stack protector.
