initialize struct sigevent before timer_create
When qemu is run under valgrind, valgrind shows the following output on exit: ==3648== 1 errors in context 2 of 2: ==3648== Syscall param timer_create(evp) points to uninitialised byte(s) ==3648== at 0x54E936A: timer_create (in /lib/librt-2.9.so) ==3648== by 0x405DCF: dynticks_start_timer (vl.c:1549) ==3648== by 0x40A966: main (vl.c:1726) ==3648== Address 0x7fefffb34 is on thread 1's stack ==3648== Uninitialised value was created by a stack allocation ==3648== at 0x405D60: dynticks_start_timer (vl.c:1534) This patch is a simple fix to remove this potential problem.
