[PATCH] posix-timers: Drop redundant memset call

[Cyrill Gorcunov <gorcunov@gmail.com>]

Initially in the commit 6891c4509c79 memset call has been
needed to clear the memory allocated on a stack, then in the
commit 2482097c6c0f memset call occasionally sneaked in regardless
the fact that we're using kmem_cache_zalloc to allocate a new timer,
lets save a few cycles dropping this call.
