Subject: s390/qeth: improve trace entries for MAC address (un)registration
Git-commit: 0969becb5f7661fb0db1a5d6b60f3d7f046ff6a7
Patch-mainline: v5.16-rc1
References: jsc#PED-594 LTC#198619

Add the failed MAC address into the trace message. Also fix up one
format string to use %x instead of %u for the CARD_DEVID.
