mm: pgtable: remove tlb_remove_page_ptdesc()

Browse Source 
The tlb_remove_ptdesc()/tlb_remove_table() is specially designed for page
table pages, and now all architectures have been converted to use it to
remove page table pages.  So let's remove tlb_remove_page_ptdesc(), it
currently has no users and should not be used for page table pages.
