Problem/Motivation

For PHP 8.1, calling the mb_strtolower() function with a null argument returns a deprecation error:

Deprecated function: trim(): Passing null to parameter #1 ($string) of type string is deprecated in block_blacklist_block_alter() (line 16 of modules/contrib/block_blacklist/block_blacklist.module).

Steps to reproduce

Proposed resolution

Add checks without breaking interface of all logic to avoid cases when null gets into mbstr func.
