wlcore: remove some unnecessary event mailbox address reads

Browse Source 
We were reading the even mailbox address three times, which was
completely unnecessary and complicated things regarding partition
selection.  Remove the unnecessry reads and set the address for
mailbox 1 and 2 after the first read.
