util/grub-protect: Correct uninit "err" variable

Browse Source 
In function protect_tpm2_export_tpm2key(), the "err" variable
is uninitialized in the normal (error free) path, so ensure this
defaults to GRUB_ERR_NONE.

This causes the GRUB build to fail with clang (observed with clang-14).

Fixes: 5934bf51c (util/grub-protect: Support NV index mode)
