can: hi311x: hi3110_open(): add check for hi3110_power_enable() return value

In hi3110_open(), the return value of hi3110_power_enable() is not checked.
If power enable fails, the device may not function correctly, while the
driver still returns success.

Add a check for the return value and propagate the error accordingly.
