REGRESSION (r169407): Calls to RenderStyle::getRoundedBorderFor() in computeRoundedRectForBoxShape() still include RenderView pointer
<http://webkit.org/b/136591>
<rdar://problem/18143731>

Reviewed by Simon Fraser.

In r169407, the RenderView* argument was removed from
RenderStyle::getRoundedBorderFor().  This argument was not
removed from these calls in computeRoundedRectForBoxShape(), but
because getRoundedBorderFor() always returned a reference, and
because the default for the next argument was true, there was no
actual change in behavior from this bug.

No new tests since there is no change in behavior.

(WebCore::computeRoundedRectForBoxShape): Remove RenderView*
arguments from calls to getRoundedBorderFor().
