drivers: infiniband: sw: rxe: fix kconfig dependency on CRYPTO

When RDMA_RXE is enabled and CRYPTO is disabled,
Kbuild gives the following 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] && INFINIBAND_VIRT_DMA [=y]

This is because RDMA_RXE selects CRYPTO_CRC32,
without depending on or selecting CRYPTO, despite that config option
being subordinate to CRYPTO.
