[PATCH 13/17] fs/select: replace __get_free_page() with kmalloc()

[Mike Rapoport (Microsoft)]

poll_get_entry() allocates new memory for poll_table entries using
__get_free_page().

kmalloc() is a better API for such use and it also provides better
scalability and more debugging possibilities.

Replace use of __get_free_page() with kmalloc().
