net: phy: micrel: fix KSZ8081/KSZ8091 cable test
Commit 21b688dabecb ("net: phy: micrel: Cable Diag feature for lan8814 phy") introduced cable_test support for the LAN8814 that reuses parts of the KSZ886x logic and introduced the cable_diag_reg and pair_mask parameters to account for differences between those chips. However, it did not update the ksz8081_type struct, so those members are now 0, causing no pairs to be tested in ksz886x_cable_test_get_status and ksz886x_cable_test_wait_for_completion to poll the wrong register for the affected PHYs (Basic Control/Reset, which is 0 in normal operation) and exit immediately. Fix this by setting both struct members accordingly.
