scsi: pm8001: Simplify pm8001_mpi_build_cmd() interface

There is no need to pass a pointer to a struct inbound_queue_table to
pm8001_mpi_build_cmd(). Passing the start index in the inbound queue table
of the adapter is enough. This change allows avoiding the declaration of a
struct inbound_queue_table pointer (circularQ variables) in many functions,
simplifying the code.

While at it, blank lines are added i(e.g. after local variable
declarations) to make the code more readable.
