nfs4_op_open: Allow open with CLAIM_PREVIOUS when FSAL supports grace period
Currently, Ganesha only allows open with CLAIM_PREVIOUS in case
`cid_allow_reclaim==true`, which requires using the `nfs4_recovery_backed`.
In case we want the FSAL to handle reclaim requests (which is signaled
by fso_grace_method) and we don't use the recovery backend we were
unable to reclaim locks. This patch will allow open with CLAIM_PREVIOUS
in case fso_grace_method is enabled, even if `cid_allow_reclaim` is not
Note that in nfs4_op_lock, in case `fso_grace_method` is enabled
we don't look at `cid_allow_reclaim` and pass it to the FSAL, as
you would expect, but before the client calls the LOCK operation
with reclaim, it opens with CLAIM_PREVOIUS, which failed with
`NFS4ERR_NO_GRACE` and so the client never even sent the reclaim
lock request.
