fix qemu exit on memory hotplug when allocation fails at prealloc time
When adding hostmem backend at runtime, QEMU might exit with error:
"os_mem_prealloc: Insufficient free host memory pages available to allocate guest RAM"
It happens due to os_mem_prealloc() not handling errors gracefully.
Fix it by passing errp argument so that os_mem_prealloc() could
report error to callers and undo performed allocation when
os_mem_prealloc() fails.
