Subject: [PATCH] nvme: tcp: fix kconfig dependency warning when !CRYPTO

When NVME_TCP is enabled and CRYPTO is disabled, it results in the
following Kbuild warning:

WARNING: unmet direct dependencies detected for CRYPTO_CRC32C
Depends on [n]: CRYPTO [=n]
Selected by [y]:
- NVME_TCP [=y] && INET [=y] && BLK_DEV_NVME [=y]

The reason is that NVME_TCP selects CRYPTO_CRC32C without depending on or
selecting CRYPTO while CRYPTO_CRC32C is subordinate to CRYPTO.

Honor the kconfig menu hierarchy to remove kconfig dependency warnings.

Fixes: 79fd751d61aa ("nvme: tcp: selects CRYPTO_CRC32C for nvme-tcp")
