fs/dax: Remove unused dax_layout_busy_page()
dax_layout_busy_page() used to let filesystems scan an entire DAX
mapping for pinned pages. All callers now use dax_break_layout(),
which also handles waiting for busy pages and deleting DAX mapping
entries once the range becomes idle.
The remaining function is only a wrapper around
dax_layout_busy_page_range() and has no in-tree users. Remove it
together with its declaration, !CONFIG_FS_DAX stub, and exported
symbol.
