NFS: Change initial mount authflavor only when server returns NFS4ERR_WRONGSEC

When attempting an initial mount, we should only attempt other
authflavors if AUTH_UNIX receives a NFS4ERR_WRONGSEC error.
This allows other errors to be passed back to userspace programs.

NFS: Fix a signed vs. unsigned secinfo bug

rpc_authflavor_t is cast from an unsigned int, but the
initial code tried to use it as a signed int. I fix
this by passing an rpc_authflavor_t pointer around, and
returning signed integers from functions.

Revert "net/sunrpc: Use static const char arrays"

This reverts commit 411b5e05617593efebc06241dbc56f42150f2abe.

Olga Kornievskaia reports:

Problem: linux client mounting linux server using rc4-hmac-md5
enctype. gssd fails with create a context after receiving a reply from
the server.

Diagnose: putting printout statements in the server kernel and
kerberos libraries revealed that client and server derived different
integrity keys.

Server kernel code was at fault due the the commit

[aglo@skydive linux-pnfs]$ git show 411b5e05617593efebc06241dbc56f42150f2abe

Trond: The problem is that since it relies on virt_to_page(), you cannot
call sg_set_buf() for data in the const section.
