migration: fix potential overflow in multifd send
I would guess it won't happen normally, but this should ease Coverity.
>>> CID
1394385: Integer handling issues (OVERFLOW_BEFORE_WIDEN)
>>> Potentially overflowing expression "pages->used * 8192U" with type "unsigned int" (32 bits, unsigned) is evaluated using 32-bit arithmetic, and then used in a context that expects an expression of type "uint64_t" (64 bits, unsigned).
854 transferred = pages->used * TARGET_PAGE_SIZE + p->packet_len;
