exec: report error when memory < hpagesize
Report an error when memory < hpagesize in file_ram_alloc() so callers
can handle the error.
If user adds a memory-backend-file object using object_add command,
specifying a size that is less than huge page size, qemu will core dump
with message:
Bad ram offset fffffffffffff000
Aborted (core dumped)
This patch fixes the problem. With this patch, qemu reports error
message like:
qemu-system-x86_64: -object memory-backend-file,mem-path=/hugepages,id=mem-file0,size=1M: memory
size 0x100000 must be equal to or larger than huge page size 0x200000
