Peter Maydell 9b1268f55c semihosting: Fix handling of buffer in TARGET_SYS_TMPNAM
The TARGET_SYS_TMPNAM implementation has two bugs spotted by
Coverity:
 * confusion about whether 'len' has the length of the string
   including or excluding the terminating NUL means we
   lock_user() len bytes of memory but memcpy() len + 1 bytes
 * In the error-exit cases we forget to free() the buffer
   that asprintf() returned to us

Resolves: Coverity CID 1490285, 1490289
