This removes superflous freezer calls as they are no longer needed
as the VFS now performs filesystem freezing/thaw if the filesystem has
support for it.
The following Coccinelle rule was used as follows:
spatch --sp-file fs-freeze-cleanup.cocci --in-place fs/$FS/
@ has_freeze_fs @
identifier super_ops;
expression freeze_op;
@@
struct super_operations super_ops = {
.freeze_fs = freeze_op,
};
@ remove_set_freezable depends on has_freeze_fs @
expression time;
statement S, S2, S3;
expression task;
