hwmon: (pmbus/core) Avoid race condition during probe
pmbus_write_smbalert_mask() is not guarded, which can cause race conditions
with concurrent sysfs attribute accesses.
Similar, PMBus accesses in pmbus_init_debugfs() are not guarded, also
resulting in potential race conditions.
Add guards to both functions to prevent the races.
