leds: flash: Prevent using uninitialized variable in flash_fault_show()
In flash_fault_show(), address of uninitialized 'fault' variable is
passed to device-specific .fault_get callbacks. This is not a problem
if such a callback directly assigns the value like rt4505_fault_get(),
but results in an undefined behavior if callback just performs bitwise
ORs like as3645a_get_fault(). So just initialize 'fault' with zero.
