[PATCH] efi: Fix free_end build warning

[geoff@infradead.org (Geoff Levand)]

Initialize the free_end variable to zero.  Fixes build warnings
like these:

  arch/arm64/kernel/efi.c: warning: ?free_end? may be used uninitialized in this function

Signed-off-by: Geoff Levand <geoff@infradead.org>

Got this with the latest arm64/for-next/core branch.  Please consider.
