wifi: b43, b43legacy: debugfs: use kzalloc() to allocate formatting buffers

b43* debugfs functions allocate 16 KiB buffers for formatting debug output
text using __get_free_pages().

kzalloc() provides a better API that does not require ugly casts and
kfree() does not need to know the size of the freed object and for 16 Kib
allocation kzalloc() will anyway delegate it to buddy.

Replace use of __get_free_pages() with kzalloc().
