Subject: [PATCH v2] scsi: mpi3mr: select CONFIG_SCSI_SAS_ATTRS

Starting with commit 42fc9fee116f ("scsi: mpi3mr: Add helper functions to
manage device's port"), kernel configured with CONFIG_SCSI_MPI3MR=m and
CONFIG_SCSI_SAS_ATTRS=n fails to build because modpost cannot find symbols
used in mpi3mr_transport.c:

ERROR: modpost: "sas_port_alloc_num" [drivers/scsi/mpi3mr/mpi3mr.ko] undefined!
ERROR: modpost: "sas_remove_host" [drivers/scsi/mpi3mr/mpi3mr.ko] undefined!
ERROR: modpost: "sas_phy_alloc" [drivers/scsi/mpi3mr/mpi3mr.ko] undefined!
ERROR: modpost: "sas_phy_free" [drivers/scsi/mpi3mr/mpi3mr.ko] undefined!
...

Select CONFIG_SCSI_SAS_ATTRS when CONFIG_SCSI_MPI3MR is enabled to prevent
inconsistent configs.

Fixes: 42fc9fee116f ("scsi: mpi3mr: Add helper functions to manage device's port")
