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.
