[PATCH v2 15/16] clk: Detect failure to set defaults

[Simon Glass]

When the default clocks cannot be set, the clock is silently probed and
the error is ignored. This is incorrect, since having the clocks at the
correct speed may be important for operation of the system.

Fix it by checking the return code.
