regulator: core: Fix error return for /sys access regulator_uV_show() is missing error handling if regulator_get_voltage_rdev() returns negative values. Instead it prints the errno as a string, e.g. -EINVAL as "-22" which could be interpreted as -22 µV. We also do not need to hold the lock while converting the integer to a string.
