The TaskMID field of struct Mpi2SCSITaskManagementRequest_t is a 16-bits little endian value. Fix the search loop in _ctl_set_task_mid() to add a cpu_to_le16() conversion before checking the value of TaskMID to avoid sparse warnings. While at it, simplify the search loop code to remove an unnecessarily complicated if condition.
