[PATCH] btrfs/delayed-inode.c: quiet sparse noise

[H Hartley Sweeten <hartleys@visionengravers.com>]

Quiet the following sparse noise:

warning: symbol 'btrfs_first_delayed_node' was not declared. Should it be static?
warning: symbol 'btrfs_next_delayed_node' was not declared. Should it be static?
warning: symbol 'btrfs_first_prepared_delayed_node' was not declared. Should it be static?
warning: symbol 'btrfs_alloc_delayed_item' was not declared. Should it be static?
warning: symbol '__btrfs_lookup_delayed_insertion_item' was not declared. Should it be static?
warning: symbol '__btrfs_lookup_delayed_deletion_item' was not declared. Should it be static?
warning: symbol '__btrfs_search_delayed_insertion_item' was not declared. Should it be static?
warning: symbol '__btrfs_search_delayed_deletion_item' was not declared. Should it be static?
warning: symbol '__btrfs_first_delayed_insertion_item' was not declared. Should it be static?
warning: symbol '__btrfs_first_delayed_deletion_item' was not declared. Should it be static?
warning: symbol '__btrfs_next_delayed_item' was not declared. Should it be static?

The functions __btrfs_lookup_delayed_deletion_item,
__btrfs_search_delayed_insertion_item, and __btrfs_search_delayed_deletion_item
are not currently being used by the code. They may be eventually, so make them
inline to for to now make sparse happy and allow the linker to discard them.
