scsi: mpt3sas: Fix _ctl_set_task_mid() TaskMID check

Browse Source 
The TaskMID field of struct Mpi2SCSITaskManagementRequest_t is a 16-bit
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.
