Add the missing curly braces so that rc is only set to zero when
it is non-zero.  Without this minor fix, rc is set to zero even
when it is zero, which is slightly redundant.

Detected with smatch static analysis.

Thanks for the patch, but I've already have a patch from Dan Carpenter queued up to fix this.
