Krzysztof Blazewicz 1ba516f475 stmhal/extint: Force 0 to 1 transition on swint(). ...

If a user tries to call `swint()` while interrupt is disabled the flag in
SWIER is set but the interrupt is not triggered and therefore the SWIER bit
is not cleared.  When the interrupt is again enabled the next call to
`swint()` won't trigger the IRQ because a 0 to 1 transition will not occur.
