Igor Mammedov 2a4e02d104 hostmem: set default prealloc_threads to valid value 
Commit 4ebc74dbbf removed default prealloc_threads initialization
by mistake, and that makes QEMU crash with division on zero at
  numpages_per_thread = numpages / memset_num_threads;
when QEMU is started with following backend
  -object memory-backend-ram,id=ram-node0,prealloc=yes,size=128M

Return back initialization removed by 4ebc74dbbf to fix issue.

Fixes: 4ebc74dbbf
