crypto: ccp - narrow scope of snp_range_list
[ Upstream commit dc8ccab15081efc4f2c5a9fc7b209cd641d29177 ]
snp_range_list is only used in __sev_snp_init_locked() in the SNP_INIT_EX
case, move the declaration there and add a __free() cleanup helper for it
instead of waiting until shutdown.
Fixes: 1ca5614b84ee ("crypto: ccp: Add support to initialize the AMD-SP for SEV-SNP")
