migration/multifd: Protect accesses to migration_threads

This doubly linked list is common for all the multifd and migration
threads so we need to avoid concurrent access.

Add a mutex to protect the data from concurrent access. This fixes a
crash when removing two MigrationThread objects from the list at the
same time during cleanup of multifd threads.

Fixes: 671326201d ("migration: Introduce interface query-migrationthreads")
