nfsd41: expand solo sequence check
Compounds consisting of only a sequence operation don't need any additional caching beyond the sequence information we store in the slot entry. Fix nfsd4_is_solo_sequence to identify this case correctly. The additional check for a failed sequence in nfsd4_store_cache_entry() is redundant, since the nfsd4_is_solo_sequence call lower down catches this case. The final ce_cachethis set in nfsd4_sequence is also redundant. Signed-off-by: Andy Adamson <andros@netapp.com> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
