vfscanf: Avoid multiple reads of multi-byte character width
This avoids a race condition if the process-global locale is changed while vfscanf is running. MB_LEN_MAX is always larger than MB_CUR_MAX, so we might realloc earlier than necessary (but even MB_CUR_MAX could be larger than the minimum required space). The existing length was a bit questionable because str + MB_LEN_MAX might point past the end of the buffer.
