[PATCH 5.4 036/152] powerpc/ptdump: Fix build failure in hashpagetable.c

[Greg Kroah-Hartman]

From: Christophe Leroy <christophe.leroy@xxxxxxxxxx>

commit 7c466b0807960edc13e4b855be85ea765df9a6cd upstream.

H_SUCCESS is only defined when CONFIG_PPC_PSERIES is defined.

!= H_SUCCESS means != 0. Modify the test accordingly.

Fixes: 65e701b2d2a8 ("powerpc/ptdump: drop non vital #ifdefs")
