[PATCH v7 01/14] mm: rename is_pinnable_pages to is_pinnable_longterm_pages

[Alex Sierra <alex.sierra@amd.com>]

is_pinnable_page() and folio_is_pinnable() were renamed to
is_longterm_pinnable_page() and folio_is_longterm_pinnable()
respectively. These functions are used in the FOLL_LONGTERM flag
context.
