powerpc: 8xx: fix a return value error in mpc8xx_pic_init
[ Upstream commit 3fd46e551f67f4303c3276a0d6cd20baf2d192c4 ]
mpc8xx_pic_init() should return -ENOMEM instead of 0 when
irq_domain_add_linear() return NULL. This cause mpc8xx_pics_init to continue
executing even if mpc8xx_pic_host is NULL.
Fixes: cc76404feaed ("powerpc/8xx: Fix possible device node reference leak")
