Subject: [PATCH] kasan: fix coccinelle warnings in kasan_p*_table

kasan_p4d_table, kasan_pmd_table and kasan_pud_table are declared as
returning bool, but return 0 instead of false, which produces a coccinelle
warning. Fix it.

Fixes: 0207df4fa1a8 ("kernel/memremap, kasan: make ZONE_DEVICE with work with KASAN")
Reported-by: kbuild test robot <lkp@...el.com>
