[RFC PATCH 01/30] x86: Revert "x86/irq: Demote irq_cpustat_t::__softirq_pending to u16"

[Frederic Weisbecker <frederic@kernel.org>]

This reverts commit 9aee5f8a7e30330d0a8f4c626dc924ca5590aba5.

We are going to need the 16 high bits above in order to implement
a softirq enable mask. x86 is the only architecture that doesn't use
unsigned int to implement softirq_pending.
