softpipe: zero-out entire clear_flags array in sp_tile_cache_flush_clear()
Before, we only cleared the flags for the active tiles (the ones inside the framebuffer bound). The problem is if we later bound a different, larger surface to the tile cache we'd have some stale clear-flags still set (and mistakenly clear some tiles in the new surface). Fixes fd.o bug 26932.
