cxl: Don't remove AFUs/vPHBs in cxl_reset
commit 4e1efb403c1c016ae831bd9988a7d2e5e0af41a0 upstream. If the driver doesn't participate in EEH, the AFUs will be removed by cxl_remove, which will be invoked by EEH. If the driver does particpate in EEH, the vPHB needs to stick around so that the it can particpate. In both cases, we shouldn't remove the AFU/vPHB.
