hwmon: (lm87) Fix masking of config register in lm87_init_client()



lm87_init_client() conditionally sets the Start bit and clears the
INT#_Clear bit in the Config 1 register.  The condition should be that
either of these bits needs changing, but currently it checks the
(self-clearing) Initialization bit instead of INT#_Clear.

Fix the condition and also ensure we never set the Initialization bit.
