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
Fixes: d579b04a52a1 ("binder: frozen notification")
