exec: add parameter errp to gethugepagesize
Add parameter errp to gethugepagesize thus callers can handle errors.
If user adds a memory-backend-file object using object_add command,
specifying a non-existing directory for property mem-path, qemu will
core dump with message:
/nonexistingdir: No such file or directory
Bad ram offset fffffffffffff000
Aborted (core dumped)
This patch fixes the problem. With this patch, qemu reports an error
message like:
qemu-system-x86_64: -object memory-backend-file,mem-path=/nonexistingdir,id=mem-file0,size=128M:
failed to get page size of file /nonexistingdir: No such file or directory
