Subject: [PATCH] sunrpc: prompt for RPCSEC_GSS_KRB5 even if NFS_V4 is enabled

NFS_V4 works fine without RPCSEC_GSS_KRB5 (even without CRYPTO).
This dependency was introduced in

	df486a2 (NFS: Fix the selection of security flavours in Kconfig)

to fix a build failure as RPCSEC_GSS_KRB5 was thought to be needed for
NFS_V4.  The fix didn't work completely as NFS_V4 didn't enforce CRYPTO
and so the select on RPCSEC_GSS_KRB5 didn't work in all situations (e.g.
arm/mx1_defconfig).

This was rectified by

	827e345 (SUNRPC: Fix the NFSv4 and RPCSEC_GSS Kconfig dependencies)

but the magic for RPCSEC_GSS_KRB5 introduced by df486a2 wasn't reverted.

Hello,

after Trond sent me the patch that later ended in 827e345702 I suggested
to fold the patch below into it[1], but without reaction and success as I
noticed just now. :-(

Best regards
Uwe
