Subject: [PATCH] arm64: KVM: rename the capability to set guest SError syndrome

In the documentation description, this capability's name is
KVM_CAP_ARM_SET_SERROR_ESR, but in the header file this
capability's name is KVM_CAP_ARM_INJECT_SERROR_ESR, so it
is better to use a same name.

Signed-off-by: Dongjiu Geng <gengdongjiu@...wei.com>

In the Documentation/virtual/kvm/api.txt:

+8.19 KVM_CAP_ARM_SET_SERROR_ESR

In the include/uapi/linux/kvm.h:
+#define KVM_CAP_ARM_INJECT_SERROR_ESR 156

So in above two files, the capability's name is not same, it
is better to use a same name.
