If snp_lookup_rmpentry() fails then "assigned" is printed in the error
message but it was never initialized.  Initialize it to false.

Fixes: dee5a47cc7a4 ("KVM: SEV: Add KVM_SEV_SNP_LAUNCH_UPDATE command")
Signed-off-by: Dan Carpenter <dan.carpenter@linaro.org>

The compiler is generally already zeroing stack variables so this doesn't cost
anything.
