dquot: Detect partial write error to quota file in write_blk() and add printk_ratelimit for quota error messages
This patch changes quota_tree.c:write_blk() to detect error caused by partial
write to quota file and add a macro to limit control printed quota error
messages so we won't fill up dmesg with a corrupted quota file.
