Subject[PATCH] IB/rxe: fix kconfig dependency warning for RDMA_RXE
Date
When RDMA_RXE is enabled and CRYPTO is disabled, it results in the
following Kbuild warning:

WARNING: unmet direct dependencies detected for CRYPTO_CRC32
Depends on [n]: CRYPTO [=n]
Selected by [y]:
- RDMA_RXE [=y] && (INFINIBAND_USER_ACCESS [=y] || !INFINIBAND_USER_ACCESS [=y]) && INET [=y] && PCI [=y] && INFINIBAND [=y] && (!64BIT || ARCH_DMA_ADDR_T_64BIT [=n])

The reason is that RDMA_RXE selects CRYPTO_CRC32 without depending on or
selecting CRYPTO while CRYPTO_CRC32 is subordinate to CRYPTO.

Honor the kconfig menu hierarchy to remove kconfig dependency warnings.

Fixes: 0812ed132178 ("IB/rxe: Change RDMA_RXE kconfig to use select")
