[PATCH] scsi: libiscsi: select CRYPTO_HASH for ISCSI_TCP

[Vegard Nossum <vegard.nossum@xxxxxxxxxx>]

Fix the following build/link error by adding a dependency on CRYPTO_HASH:

  ld: drivers/scsi/libiscsi_tcp.o: in function `iscsi_tcp_dgst_header':
  libiscsi_tcp.c:(.text+0x237): undefined reference to `crypto_ahash_digest'
  ld: drivers/scsi/libiscsi_tcp.o: in function `iscsi_tcp_segment_done':
  libiscsi_tcp.c:(.text+0x1325): undefined reference to `crypto_ahash_final'

Fixes: 5d6ac29b9ebf2 ("iscsi_tcp: Use ahash")
