Fix potential vulnerable cloned functions

[npt-1707]

Hi Development team,

I identified vulnerabilities in a clone function sdsMakeRoomFor() in ext/hiredis-0.14.1/sds.c sourced from redis/redis. These issues, originally reported in CVE-2021-41099, were resolved in the redis repository via this commit https://github.com/redis/redis/commit/c6ad876774f3cc11e32681ea02a2eead00f2c521.

This PR applies the corresponding patch to fix the vulnerabilities in this codebase.

Please review at your convenience. Thank you for your time and attention!
