[PATCH] mm/folio-compat: Drop superfluous return statements in void compat wrappers

[Hongfu Li <hongfu.li@linux.dev>]

From: Hongfu Li <lihongfu@kylinos.cn>

unlock_page(), end_page_writeback() and wait_on_page_writeback()
are void wrappers forwarding to folio-based functions which also
return void. Explicit return statements here are syntactically valid
but unnecessary, and inconsistent with other nearby compat helpers
such as mark_page_accessed() and set_page_writeback().

Drop all these superfluous return keywords.
