openocd: remove NULL comparisons with checkpatch [1/2]

Patch generated automatically through the new checkpatch with
flags "--types COMPARISON_TO_NULL --fix-inplace".
This only fixes the comparisons
	if (symbol == NULL)
	if (symbol != NULL)
The case of NULL on the left side of the comparison is not tested.

Some automatic fix is incorrect and has been massaged by hands:
	-	if (*psig == NULL)
	+	if (*!psig)
changed as
	+	if (!*psig)
