firewire: sbp2: protect a reference counter properly
The assertion in the comment in sbp2_allow_block() is no longer true. Or maybe it never was true. At least now, the sole caller of sbp2_allow_block(), sbp2_login, can run concurrently to one of sbp2_unblock()'s callers, sbp2_remove. sbp2_login is performed by sbp2_logical_unit.work. sbp2_remove is performed by fw_device.work. sbp2_remove cancels sbp2_logical_unit.work, but only after it called sbp2_unblock.
