Subject: kvm: arm64: Fix EC field in inject_abt64

From: Matt Evans <matt.evans@arm.com>

commit e4fe9e7dc3828bf6a5714eb3c55aef6260d823a2 upstream.

The EC field of the constructed ESR is conditionally modified by ORing in
ESR_ELx_EC_DABT_LOW for a data abort.  However, ESR_ELx_EC_SHIFT is missing
from this condition.
