[Qemu-devel] [PATCH v3 1/2] s390x/css: use macro for event-information pending error recover code

[Dong Jia Shi <bjsdjshi@linux.vnet.ibm.com>]

Let's use a macro for the ERC (error recover code) when generating a
Channel Subsystem Event-information pending CRW (channel report word).

While we are at it, let's also add all other ERCs.
