KVM: SEV-ES: reduce ghcb_sa_len to 32 bits
The size of the GHCB scratch area is limited to 16 KiB (GHCB_SCRATCH_AREA_LIMIT),
so there is no need for it to be a u64. This fixes a build error on 32-bit
systems:
i686-linux-gnu-ld: arch/x86/kvm/svm/sev.o: in function `sev_es_string_io:
sev.c:(.text+0x110f): undefined reference to `__udivdi3'
Cc: stable@vger.kernel.org
Fixes: 019057bd73d1 ("KVM: SEV-ES: fix length of string I/O")
