orangefs: validate getxattr response length
orangefs_inode_getxattr() trusts the userspace-client-controlled
downcall.resp.getxattr.val_sz and uses it as a memcpy() length
both for the temporary user buffer and the cached xattr buffer.
Reject malformed negative or oversized lengths before copying
response bytes.
