selftests/arm64: Remove casts to/from void in check_tags_inclusion

Browse Source 
Void pointers may be freely used with other pointer types in C, any casts
between void * and other pointer types serve no purpose other than to
mask potential warnings. Drop such casts from check_tags_inclusion to
help with future review of the code.
