    [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..
