when call utf16s_to_utf8s, last parmater 'maxout' will be reduced
with the returned value of utf32_to_utf8, the value reflects the
size of one utf character, it could be 1~max charset size(3), so
maxout should use MAX_NAME_LENGTH * MAX_CHARSET_SIZE
when call utf8s_to_utf16s, the inlen will be reduced with the
the returned value of utf8_to_utf32, so it should use
MAX_NAME_LENGTH * MAX_CHARSET_SIZE or the lenghth of p_cstring whose
max value is MAX_NAME_LENGTH * MAX_CHARSET_SIZE.

utf8s_to_utf16s could return -EINVAL(-22), then uniname[i] =
uniname[-22] = '\0' will corrupt other local variable.
uniname is a local variable having different address everytime
when call nls_cstring_to_uniname. so uniname[-22] could corrupt
some different addresses.
and also when filename reaches at maximum length, need to leave
last one space in buffer for '\0'
