leds: is31fl319x: Wrap mutex_destroy() for devm_add_action_or_rest()

Clang complains that devm_add_action() takes a parameter with a wrong type:

warning: cast from 'void (*)(struct mutex *)' to 'void (*)(void *)' converts to incompatible function type [-Wcast-function-type-strict]
    err = devm_add_action(dev, (void (*)(void *))mutex_destroy, &is31->lock);
                               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    1 warning generated.

It appears that the commit e1af5c8 ("leds: is31fl319x: Fix devm vs.
non-devm ordering") missed two things:

- whilst the commit mentions devm_add_action_or_reset() the actual change
  utilised devm_add_action() call by mistake
- strictly speaking the parameter is not compatible by type

Fix both issues by switching to devm_add_action_or_reset() and adding a
wrapper for mutex_destroy() call.
