powerpc/process: Fix sparse address space warnings
This patch fixes the following warnings, which are leftovers
from when __get_user() was replaced by probe_kernel_address().
arch/powerpc/kernel/process.c:1287:22: warning: incorrect type in argument 2 (different address spaces)
arch/powerpc/kernel/process.c:1287:22: expected void const *src
arch/powerpc/kernel/process.c:1287:22: got unsigned int [noderef] <asn:1>*<noident>
arch/powerpc/kernel/process.c:1319:21: warning: incorrect type in argument 2 (different address spaces)
arch/powerpc/kernel/process.c:1319:21: expected void const *src
arch/powerpc/kernel/process.c:1319:21: got unsigned int [noderef] <asn:1>*<noident>
Fixes: 7b051f665c32d ("powerpc: Use probe_kernel_address in show_instructions")
