gallium/hud: check NULL return from u_upload_alloc
Fixes the following segmentation fault:
signal SIGSEGV: invalid address (fault address: 0x0)
frame #0: 0x00007fffe718e117 radeonsi_dri.so hud_draw_background_quad hud_context.c:170
167
168 assert(hud->bg.num_vertices + 4 <= hud->bg.max_num_vertices);
169
-> 170 vertices[num++] = (float) x1;
171 vertices[num++] = (float) y1;
172
173 vertices[num++] = (float) x1;
