[BUG] A large negative number(e.g. -LONG_MAX) in HRANDFIELD/ZRANDMEMBER can easily cause Valkey to crash.

Describe the bug

When using the HRANDFIELD or ZRANDMEMBER commands, if an extremely negative value(e.g. -LONG_MAX) is provided, the memory will continue to rise and eventually cause Redis to crash.

To reproduce

HRANDFIELD hash -9223372036854775807

Expected behavior

IMHO, it is more reasonable to set a limit on count according to the memory limit or the actual size of the hash table to prevent Redis from crashing. This can prevent crashes caused by careless and incorrect use. If a user really needs to sample a lot of elements that allow duplicates, he can achieve the same purpose by calling the command multiple times.
