scsi: tcm_fc: use target_remove_session 

This converts tcm_fc to use target_remove_session

tcm_fc was calling transport_deregister_session_configfs then calling
transport_deregister_session when commands have completed. It should be ok
for it to call transport_deregister_session_configfs later via
target_remove_session because transport_deregister_session_configfs only
prevents access from configfs via tpg removal and its call to the
close_session callback for that driver, and this is already protected by
the ft_lport_lock and its port lookup handling.
