[SCSI] hpsa: removed unneeded structure member max_sg_entries and fix badly named constant MAXSGENTRIES
We had both h->max_sg_entries and h->maxsgentries in the per controller structure which is terribly confusing. max_sg_entries was really just a constant, 32, which defines how big the "block fetch table" is, which is as large as the max number of SG elements embedded within a command (excluding SG elements in chain blocks). MAXSGENTRIES was the constant used to denote the max number of SG elements embedded within a command, also a poor name. So renamed MAXSGENTREIS to SG_ENTRIES_IN_CMD, and removed h->max_sg_entries and replaced it with SG_ENTRIES_IN_CMD. h->maxsgentries is unchanged, and is the maximum number of sg elements the controller will support in a command, including those in chain blocks, minus 1 for the chain block pointer..
