The recv variable in sandbox_tpm2_fill_buf() is a pointer on a pointer
of a char array. It means accessing *recv is the char array pointer
itself while **recv is the first character of that array. There is no
need for such indirection here, so simplify the code.
Simplifying things will make the last assignment right: "*recv = NULL"
is now correct. The issue has been found by the following Coverity
Scan report:
CID 183371: Incorrect expression (UNUSED_VALUE)
Assigning value "4UL" to "*recv" here, but that stored value is overwritten before it can be used.
232 *recv += sizeof(rc);
233
234 /* Add trailing \0 */
235 *recv = NULL;
While at simplifying things, use '\0' instead of NULL when adding an
empty char at the end of the buffer.
