scsi: mpi3mr: Fix some kernel-doc warnings in scsi_bsg_mpi3mr.h

Correct the name of a struct in kernel-doc to match the actual function
name.

Add kernel-doc comments for 2 reserved fields to match comments for other
reserved fields.

Correct the kernel-doc comments for a nested struct to eliminate kernel-doc
warnings for them.

Warnings fixed here are:

scsi_bsg_mpi3mr.h:419: warning: expecting prototype for struct mpi3mr_bsg_buf_entry_list. Prototype was for struct mpi3mr_buf_entry_list instead

scsi_bsg_mpi3mr.h:435: warning: Function parameter or struct member 'rsvd2' not described in 'mpi3mr_bsg_mptcmd'
scsi_bsg_mpi3mr.h:456: warning: Function parameter or struct member 'rsvd3' not described in 'mpi3mr_bsg_packet'

scsi_bsg_mpi3mr.h:456: warning: Excess struct member 'drvrcmd' description in 'mpi3mr_bsg_packet'
scsi_bsg_mpi3mr.h:456: warning: Excess struct member 'mptcmd' description in 'mpi3mr_bsg_packet'
