arm64: efi: Revert "Recover from synchronous exceptions ..."

This reverts commit 3b5015f4b5e85887, which introduced some code in
assembler that manipulates both the ordinary and the shadow call stack
pointer in a way that could potentially be taken advantage of. So let's
revert it, and do a better job the next time around.
