Subject: [PATCH] scsi: scsi_transport_sas: select BLK_DEV_BSGLIB

Without CONFIG_BLK_DEV_BSGLIB, we get a link error here:

drivers/scsi/scsi_transport_sas.o: In function `sas_bsg_initialize':
scsi_transport_sas.c:(.text+0xcc0): undefined reference to `bsg_setup_queue'
scsi_transport_sas.c:(.text+0xd10): undefined reference to `bsg_setup_queue'
drivers/scsi/scsi_transport_sas.o: In function `sas_smp_dispatch':
scsi_transport_sas.c:(.text+0xe8c): undefined reference to `bsg_job_done'

This modifies the Kconfig 'select' statement accordingly, and matching
what we do for the other two scsi_transport implementations that use
bsglib.

Fixes: 651a01364994 ("scsi: scsi_transport_sas: switch to bsg-lib for SMP passthrough")
