futex: Remove unused empty compat_exit_robust_list()
Commit ba31c1a48538 ("futex: Move futex exit handling into futex code")
introduced compat_exit_robust_list() with a full-fledged implementation for
CONFIG_COMPAT, and an empty-body function for !CONFIG_COMPAT.
However, compat_exit_robust_list() is only used in futex_mm_release() under
#ifdef CONFIG_COMPAT.
Hence for !CONFIG_COMPAT, make CC=clang W=1 warns:
kernel/futex.c:314:20:
warning: unused function 'compat_exit_robust_list' [-Wunused-function]
There is no need to declare the unused empty function for !CONFIG_COMPAT.
Simply remove it.
