Staging: iio: accel: sca3000: Fixed NULL comparison style

The variable u8 **rx_p, is a pointer-to-pointer and hence the check
should

In the earlier version, checkpatch.pl gave the following check, which
was incorrect:
CHECK: Comparison to NULL could be written "!rx_p"
+       if (*rx_p == NULL) {
