freedreno/ir3: Handle instr->address when cloning

Without this, a cloned instruction that takes full regs will trigger an
ir3_validate assert.  This can happen, for ex, if an instruction that
writes p0.x and has a relative src gets cloned in ir3_sched.

Fixes an assert in Genshin Impact with a debug build.
