[PATCH] selftests/filesystems: remove the unused list_del()

[Sasha Levin]

Nothing uses list_del() in utils.c, and clang warns about it in each
test that builds utils.c with -Wall:

  ../utils.c:106:20: warning: unused function 'list_del' [-Wunused-function]

Remove it.

Found with clang 21; KernelCI's clang builds show the same warning.
