[PATCH] powerpc/pseries: Disable relocation on exception while going down during crash.

From: Mahesh Salgaonkar <mahesh at linux.vnet.ibm.com>

Disable relocation on exception while going down even in kdump case. This
is because we are about clear htab mappings while kexec-ing into kdump
kernel and we may run into issues if we still have AIL ON.
