From: Arnd Bergmann <arnd@arndb.de>
Switching virtio-blk to the sg_pool interfaces causes a build failures when they are not part of the kernel:
drivers/block/virtio_blk.c:182:3: error: implicit declaration of function 'sg_free_table_chained' [-Werror,-Wimplicit-function-declaration] sg_free_table_chained(&vbr->sg_table, ^ drivers/block/virtio_blk.c:195:8: error: implicit declaration of function 'sg_alloc_table_chained' [-Werror,-Wimplicit-function-declaration] err = sg_alloc_table_chained(&vbr->sg_table, ^
Select this symbol through Kconfig, as is done for all other users.
