Peter Maydell 4bcb7de072 migration: Define BLK_MIG_BLOCK_SIZE as unsigned long long
When we use BLK_MIG_BLOCK_SIZE in expressions like
block_mig_state.submitted * BLK_MIG_BLOCK_SIZE, this multiplication
is done as 32 bits, because both operands are 32 bits.  Coverity
complains about possible overflows because we then accumulate that
into a 64 bit variable.

Define BLK_MIG_BLOCK_SIZE as unsigned long long using the ULL suffix.
The only two current uses of it with this problem are both in
block_save_pending(), so we could just cast to uint64_t there, but
using the ULL suffix is simpler and ensures that we don't
accidentally introduce new variants of the same issue in future.

Resolves: Coverity CID 1487136, 1487175
