[RFC PATCH 1/6] softirq: Turn set_softirq_pending() to reset_softirq_pending()

From: Frederic Weisbecker
Date: Tue Aug 01 2023 - 09:24:56 EST


set_softirq_pending() is only ever used to reset the pending vector's
mask to 0. Make the function more specialized for that very purpose and
rename it accordingly.
