migration: fix uninitialized variable warning in migrate_send_rp_req_pages()
After the WITH_QEMU_LOCK_GUARD macro is added, the compiler cannot identify
that the statements in the macro must be executed. As a result, some variables
assignment statements in the macro may be considered as unexecuted by the compiler.
When the -Wmaybe-uninitialized capability is enabled on GCC9,the compiler showed warning:
migration/migration.c: In function ‘migrate_send_rp_req_pages’:
migration/migration.c:384:8: warning: ‘received’ may be used uninitialized in this function [-Wmaybe-uninitialized]
384 | if (received) {
| ^
Add a default value for 'received' to prevented the warning.
