[PATCH] mm/mmu_gather: remove @delay_remap of __tlb_remove_page_size()

[PATCH] mm/mmu_gather: remove @delay_remap of __tlb_remove_page_size()

[Wei Yang]

Functioin __tlb_remove_page_size() is only used in
tlb_remove_page_size() with @delay_remap set to false and it is passed
directly to __tlb_remove_folio_pages_size().

Remove @delay_remap of __tlb_remove_page_size() and call
__tlb_remove_folio_pages_size() with false @delay_remap.
