binder: fix BINDER_WORK_FROZEN_BINDER debug logs

The BINDER_WORK_FROZEN_BINDER type is not handled in the binder_logs
entries and it shows up as "unknown work" when logged:

  proc 649
  context binder-test
    thread 649: l 00 need_return 0 tr 0
    ref 13: desc 1 node 8 s 1 w 0 d 0000000053c4c0c3
    unknown work: type 10

This patch add the freeze work type and is now logged as such:

  proc 637
  context binder-test
    thread 637: l 00 need_return 0 tr 0
    ref 8: desc 1 node 3 s 1 w 0 d 00000000dc39e9c6
    has frozen binder
