[PATCH v3] Staging: vt6656: Checkpatch fix: else after break or return

[Emrys Bayliss]

This patch fixes the following checkpatch.pl error:
rxtx.c:558: WARNING: else is not generally useful after a break or return

Signed-off-by: Emrys Bayliss <emrys@paradise.net.nz>
---
The else statement was replaced with a block to avoid the following
compiler error:
"warning: ISO C90 forbids mixed declarations and code"
due to this declaration:
struct vnt_cts *buf = &head->cts_g; (line 559)

Is there a better way such as using head (a union) directly instead?

The last patch I sent removed the return 0. Since this isn't related to
the error in the title I left it for a separate patch.

As I said before, this is not correct, please fix it up properly.
