btrfs: fix empty_zero_page misusage
Heiko Carstens noticed that btrfs was using empty_zero_page
incorrectly. He explained:
The definition of empty_zero_page is architecture specific. It
is (currently) either a character array, an unsigned long
containing the address of the empty_zero_page, or even worse
only the address of the struct page belonging to the
empty_zero_page.
This commit changes btrfs to use a for-loop instead. On x86
the resulting .ko is smaller, and we're no longer worrying about
how each arch builds its zeros.
