posix-cpu-timers: Fix nanosleep task_struct leak
commit e6c42c295e071dd74a66b5a9fcf4f44049888ed8 upstream.
The trinity fuzzer triggered a task_struct reference leak via
clock_nanosleep with CPU_TIMERs. do_cpu_nanosleep() calls
posic_cpu_timer_create(), but misses a corresponding
posix_cpu_timer_del() which leads to the task_struct reference leak.
