Re: [U-Boot] common: hash: zero end the string instead of the pointer

if algo->digest_size is zero nothing is set in the str_output buffer. An attempt is made to zero end the buffer, but the pointer to the buffer is set to zero instead. I am unaware if it causes any actual problems, but solves the following warning:

common/hash.c:217:13: warning: expression which evaluates to zero treated as a null pointer constant of type 'char *' [-Wnon-literal-null-conversion] str_ptr = '\0'; ^~~~
