A recent change removed the dependency on BLK_DEV_NVME, which implies
the dependency on PCI and BLOCK. We don't need CONFIG_PCI, but without
CONFIG_BLOCK we get tons of build errors, e.g.

In file included from drivers/nvme/host/core.c:16:0:
linux/blk-mq.h:182:33: error: 'struct gendisk' declared inside parameter list will not be visible outside of this definition or declaration [-Werror]
drivers/nvme/host/core.c: In function 'nvme_setup_rw':
drivers/nvme/host/core.c:295:21: error: implicit declaration of function 'rq_data_dir' [-Werror=implicit-function-declaration]
drivers/nvme/host/nvme.h: In function 'nvme_map_len':
drivers/nvme/host/nvme.h:217:6: error: implicit declaration of function 'req_op' [-Werror=implicit-function-declaration]
drivers/nvme/host/scsi.c: In function 'nvme_trans_bdev_limits_page':
drivers/nvme/host/scsi.c:768:85: error: implicit declaration of function 'queue_max_hw_sectors' [-Werror=implicit-function-declaration]

This adds back the specific CONFIG_BLOCK dependency to avoid broken
configurations.

Thanks Arnd, queued for the next round of rc fixes.

With a slight modification to the component in the subject line
(nvme-rdma).

Shouldn't we just have a if BLOCK around all the entries in the Kconfig?
