[PATCH] firewire: core: remove useless lockdep_assert_held()

The bm_work work item should be scheduled after holding fw_card reference
counting. At a commit 25feb1a96e21 ("firewire: core: use cleanup function
in bm_work"), I misinterpreted it as fw_card spinlock and inserted
lockdep_assert_hold() wrongly.

This commit removes the useless line.
