    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.

Please use git sent-email to send patches and please fix crypto Kconfig
to enable CRYPTO if CRYPTO_* selected.

It is a little bit awkward to request all users of CRYPTO_* to request
select CRYPTO too.

Thanks
