NFSv4.1: allow nfs_fhget to succeed with mounted on fileid
Commit 28331a46d88459788c8fca72dbb0415cd7f514c9 "Ensure we request the
ordinary fileid when doing readdirplus"
changed the meaning of NFS_ATTR_FATTR_FILEID which used to be set when
FATTR4_WORD1_MOUNTED_ON_FILED was requested.
Allow nfs_fhget to succeed with only a mounted on fileid when crossing
a mountpoint or a referral.
Ask for the fileid of the absent file system if mounted_on_fileid is not
supported.
