migration: Clean up signed vs. unsigned XBZRLE cache-size
73af8dd8d7 "migration: Make xbzrle_cache_size a migration
parameter" (v2.11.0) made the new parameter unsigned (QAPI type
'size', uint64_t in C). It neglected to update existing code, which
continues to use int64_t.
migrate_xbzrle_cache_size() returns the new parameter. Adjust its
return type.
QMP query-migrate-cache-size returns migrate_xbzrle_cache_size().
Adjust its return type.
migrate-set-parameters passes the new parameter to
xbzrle_cache_resize(). Adjust its parameter type.
xbzrle_cache_resize() passes it on to cache_init(). Adjust its
parameter type.
