[PATCH] nouveau/secboot/gm20b: initialize pointer in gm20b_secboot_new()

[Dan Carpenter]

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.

Fixes: 923f1bd27bf1 ("drm/nouveau/secboot/gm20b: add secure boot support")

Static analysis.  I'm not sure how this is called.
