[media] drxk: Remove the CHK_ERROR macro

The CHK_ERROR macro does a flow control, violating chapter 12
of the Documentation/CodingStyle. Doing flow controls inside
macros is a bad idea, as it hides what's happening. It also
hides the var "status" with is also a bad idea.

The changes were done by this small perl script:
	my $blk=0;
	while (<>) {
		s /^\s+// if ($blk);
		$f =~ s/\s+$// if ($blk && /^\(/);
		$blk = 1 if (!m/\#/ && m/CHK_ERROR/);
		$blk=0 if ($blk && m/\;/);
		s/\n/ / if ($blk);
		$f.=$_;
	};
	$f=~ s,\n(\t+)CHK_ERROR\((.*)\)\;([^\n]*),\n\1status = \2;\3\n\1if (status < 0)\n\1\tbreak;,g;
	print $f;

And manually fixed.
