freedreno: Fix OUT_REG() on address regs without a .bo supplied.

Browse Source 
Sometimes you want to zero out an address by supplying a NULL BO, but
without this we would end up only emitting one dword.  Increases size of
fd6_gmem.o by .8%, though it's not clear to me why (no obvious terrible
codegen happening)
