drm/etnaviv: Fix NULL dereference on unbind without PPU flop reset
flop_reset_data_ppu is only allocated on GPUs that need the PPU flop
reset. However, etnaviv_unbind(..) frees it unconditionally, and
etnaviv_cmdbuf_free(..) dereferences cmdbuf->suballoc before checking
whether cmdbuf is NULL.
As a result, unloading the driver on GPUs that do not need the PPU
flop reset causes a NULL pointer dereference at address 0.
