posix-timers: Drop redundant memset() invocation

Initially in commit 6891c4509c79 memset() was required to clear a variable
allocated on stack. Commit 2482097c6c0f removed the on stack variable and
retained the memset() despite the fact that the memory is allocated via
kmem_cache_zalloc() and therefore zereoed already.

Drop the redundant memset().
