hwmon: (pmbus/core) clear faults after setting smbalert mask
pmbus_write_smbalert_mask() ignores the errors if the chip can't set
smbalert mask the standard way. It is not necessarily a problem for the irq
support if the chip is otherwise properly setup but it may leave an
uncleared fault behind.
pmbus_core will pick the fault on the next register_check(). The register
check will fails regardless of the actual register support by the chip.
This leads to missing attributes or debugfs entries for chips that should
provide them.
We cannot rely on register_check() as PMBUS_SMBALERT_MASK may be read-only.
Unconditionally clear the page fault after setting PMBUS_SMBALERT_MASK to
avoid the problem.
