The legacy client tracking infrastructure of nfsd makes use of MD5 to
derive a client's recovery directory name. As the nfsd module doesn't
declare any dependency on CRYPTO_MD5, though, it may fail to allocate
the hash if the kernel was compiled without it. As a result, generation
of client recovery directories will fail with the following error:
NFSD: unable to generate recoverydir name
The dependency was removed as a seemingly redundant dependency back in
6aaa67b5f3b9 (NFSD: Remove redundant "select" clauses in fs/Kconfig
2008-02-11). But in fact, even then the MD5 module was pulled in only
when RPCSEC_GSS_KRB5 or RPCSEC_GSS_KRB5 was selected.
Fix the issue by adding back an explicit dependency on CRYPTO_MD5.
