[ Upstream commit b46c5fa57cc60692412f616ac66ab624a941fdb3 ]

The CXL spec (3.0, section 8.2.9.8.4) Lists Inject Poison and Clear
Poison as having the effects of "Immediate Data Change". Fix this in the
mock driver so that the command effect log is populated correctly.

Fixes: 371c16101ee8 ("tools/testing/cxl: Mock the Inject Poison mailbox command")
