[PATCH tip:timers/core] kernel/posix-timers.c: Fix unused variable

[Pavel Emelyanov <xemul@parallels.com>]

The kbuild test robot detected unused variable introduced by commit 5ed67f05 (posix
timers: Allocate timer id per process (v2)).

   kernel/posix-timers.c: In function '__posix_timers_find':
   kernel/posix-timers.c:157:21: warning: unused variable 'node' [-Wunused-variable]

This var is just not needed.
