[patch] regulator: core: remove some unneeded conditions

[Dan Carpenter <dan.carpenter@oracle.com>]

These always true or always false conditions cause static checker
warnings.

The check prior to checking "if (pin->enable_count <= 1) {" is
"if (pin->enable_count > 1) ", so we know that ->enable_count is <= 1
already and can delete the check.

The queue_delayed_work() function is type bool so the return value can
never be less than zero.
