nfs: make subdir mounting work for Solaris 10 clients

This fixes the segfault caused by solaris client in Gluster/NFS.
Volname was not being parsed properly, Instead of volume
name complete path was being used in nfs_mntpath_to_xlator().
Fixed it by striping volume name from complete path  in nfs_mntpath_to_xlator().

Modified function name nfs3_funge_solaris_zerolen_fh() to
nfs3_funge_webnfs_zerolen_fh() as zero-filled filehandle is specific to WebNFS.
RFC : https://tools.ietf.org/html/rfc2055
Solaris uses WebNFS, the zero-filled FH is defined in the WebNFS spec.

Logic was even added in fuction nfs3_funge_webnfs_zerolen_fh() to send
subdir path in function glfs_resolve_at() instead of complete path for
subdir mount.
