Mahesh Salgaonkar 4c0e24ab73 powerpc/fadump: Unregister fadump on kexec down path. 
commit 722cde76d6 upstream.

Unregister fadump on kexec down path otherwise the fadump registration
in new kexec-ed kernel complains that fadump is already registered.
This makes new kernel to continue using fadump registered by previous
kernel which may lead to invalid vmcore generation. Hence this patch
fixes this issue by un-registering fadump in fadump_cleanup() which is
called during kexec path so that new kernel can register fadump with
new valid values.

Fixes: b500afff11 ("fadump: Invalidate registration and release reserved memory for general use.")
