1) create a pool of high priority message frames in the region of memory between message frames and chains. The modifications are in _base_allocate_memory_pools. Also create a seperate pool of memory for internal commands located near the same region of memory. The pool of high priority message frames is restriced by the facts->HighPriorityCredit. 2) Create additional API for accessing request message frames. New function mpt2sas_base_get_smid_hpr is for highpriority request. New function mpt2sas_base_get_smid_scsiio for SCSI_IO, passing in the scsi command pointer. The mpt2sas_base_get_smid function is for requesting internal commands. 3) Added new function _base_get_cb_idx to obtain the callback index from one of the three pools of request message frames. 4) Removed wrapper functions _scsih_scsi_lookup_set and _scsih_scsi_lookup_getclear. These were removed because this handling was moved into mpt2sas_base_get_smid_scsiio and mpt2sas_base_free_smid. 5) The function mpt2sas_base_free_smid is modified so the request message frames are put back on one of the three pools of request message frames.
