Fix rdb.c var types when calling rdbLoadLen().

Technically as soon as Redis 64 bit gets proper support for loading
collections and/or DBs with more than 2^32 elements, the 32 bit version
should be modified in order to check if what we read from rdbLoadLen()
overflows. This would only apply to huge RDB files created with a 64 bit
instance and later loaded into a 32 bit instance.
