Log Message:
Avoid prepending a timestamp to lock debug outputs on ddb

Lock printer functions (lockops_t#lo_dump) use printf_nolog to print, but
printf_nolog now prepends a timestamp which is unnecessary for ddb:

    db{0}> show all locks/t
    [Locks tracked through LWPs]
    Locks held by an LWP (iperf):
    Lock 0 (initialized at soinit)

    [ 79103.0868574] owner field  : 0xffffedeb7dfdb240 wait/spin:                1/0

Fix it by passing a printer function to lo_dump functions, i.e., make the
functions use db_printf on ddb.
