WARN_ONCE(): use bool for boolean flag
Commit 70867453092297be9afb2249e712a1f960ec0a09 ("printk_once(): use bool
for boolean flag") changed printk_once() to use bool instead of int for
its guard variable. Do the same change to WARN_ONCE() and WARN_ON_ONCE(),
for the same reasons.
This resulted in a reduction of 1462 bytes on a x86-64 defconfig:
