regulator: Fix regression due to NULL constraints check
The commit [39f802d6b6d9: 'regulator: Build sysfs entries with static
attribute groups'] converted the sysfs entry creation to static
attribute groups, but this resulted in a regression due to the NULL
check of rdev->constraints. At the point where the device is
registered, rdev->constraints isn't set, so the attributes depending
on it are missing.
We may fix it by shuffling the code order in regulator_register(), but
a quicker fix is to just remove this NULL check. rdev->constraints is
in anyway always set to non-NULL in set_machine_constraints(), thus
the check there is basically superfluous.
Fixes: 39f802d6b6d9 ('regulator: Build sysfs entries with static attribute groups')
