Rusty Russell 2ac775f9f4 lightningd: fix crash with -O3 -flto.

It's foolish to ban passing NULL, 0 to memcpy, memset et al, but
it's been done.  At high level of optimization, GCC assumes this doesn't
happen, and yep, assumes "if (ctx)" inside tal_free() must be true.

So when a psbt is NULL, and psbt_get_bytes returns NULL, a crash ensues:
