Clang does not like qmp_migrate_set_downtime()'s code to clamp double
@value to 0..INT64_MAX:
qemu/migration/migration.c:2038:24: error: implicit conversion from 'long' to 'double' changes value from 9223372036854775807 to 9223372036854775808 [-Werror,-Wimplicit-int-float-conversion]
The warning will be enabled by default in clang 10. It is not
available for clang <= 9.
The clamp is actually useless; @value is checked to be within
0..MAX_MIGRATE_DOWNTIME_SECONDS immediately before. Delete it.
While there, make the conversion from double to int64_t explicit.
