[PATCH] NFSv4.1: Ensure 'nfs4_sp4_select_mode()' can report -EINVAL when needed

[Christophe JAILLET]

Since commit 937e3133cd0b, 'nfs4_sp4_select_mode()' always return 0.
Based on the way this commit is written (direct return replaced by some
'ret = -EXXX'), it is likely that returning this error code is expected.

Fixes: 937e3133cd0b ("NFSv4.1: Ensure we clear the SP4_MACH_CRED flags in nfs4_sp4_select_mode()")
