drm/nouveau/secboot/gm20b: initialize pointer in gm20b_secboot_new()

Browse source 
[ Upstream commit 3613a9bea95a1470dd42e4ed1cc7d86ebe0a2dc0 ]

We accidentally set "psb" which is a no-op instead of "*psb" so it
generates a static checker warning.  We should probably set it before
the first error return so that it's always initialized.
