target: replace various cmd flags with a transport state
Replace various atomic_ts used as flags in struct se_cmd with a single transport_state bitmap that requires t_state_lock to be held for modifications. In the target core that assumption generally is true, but some recently added code in the SRP target had to grow new lock calls. I can't say I like the way how it messes with the command state directly, but let's leave that for later. (Re-add missing ib_srpt.c changes that nab dropped..)
