Modify ata_scsiop_mode_sense() and ata_msense_control() to support mode
sense access to the T2A and T2B sub-pages of the control mode page.
ata_msense_control() is modified to support sub-pages. The T2A sub-page
is generated using the read descriptors of the command duration limits
log page 18h. The T2B sub-page is generated using the write descriptors
of the same log page. With the addition of these sub-pages, getting all
sub-pages of the control mode page is also supported by increasing the
value of ATA_SCSI_RBUF_SIZE from 576B up to 2048B to ensure that all
sub-pages fit in the fill buffer.
