Do proper error handling in d_mark_tmpfile_name() by returning errors rather than using BUG_ON()'s. Adjust caller to check for errors from d_mark_tmpfile_name() as well as clean it up for using return value from scnprintf() in QSTR_LEN() to make it more obvious where the tmpfile name's length is coming from.
