This patch updates the round_rate() logic here to return zero instead of a
negative number on error.

In conjunction with higher-level changes associated with acting on the
return value of clk_ops->round_rate() it is then possible to have
clk_ops->round_rate() return values from 1 Hz to ULONG_MAX Hz instead of
the current limitation of 1 Hz to LONG_MAX Hz.
