Subject: [PATCH] target: Drop unnecessary CMD_T_DEV_ACTIVE check from
 transport_lun_remove_cmd

This patch drops an unnecessary acquire/release of se_cmd->t_state_lock within
transport_lun_remove_cmd() when checking CMD_T_DEV_ACTIVE for invoking
target_remove_from_state_list().

For all fast path completion cases, transport_lun_remove_cmd() is always
called ahead of transport_cmd_check_stop(), and since transport_cmd_check_stop()
is calling target_remove_from_state_list() when remove_from_lists=true,
the t_state_lock usage in transport_lun_remove_cmd() can safely be removed.
