[PATCH v5 15/17] xfs: mount-api - dont set sb in xfs_mount_alloc()

[Ian Kent <raven@themaw.net>]

When changing to use the new mount api the super block won't be
available when the xfs_mount info struct is allocated so move
setting the super block in xfs_mount to xfs_fs_fill_super().

Also change xfs_mount_alloc() decalaration static -> STATIC.
