target: avoid checking for non NULL pointer to free it
The function free() can be called with a NULL pointer as argument,
no need to check the argument before. If the pointer is NULL, no
operation is performed by free().
Remove the occurrences of pattern:
if (ptr)
free(ptr);
In target/openrisc/jsp_server.c, an error is logged if the ptr was
already NULL. This cannot happen since the pointer was already
referenced few lines before and openocd would have been already
SIGSEGV in that case, so remove the log.
