dax,ext2: replace ext2_clear_xip_target with dax_clear_blocks
This is practically generic code; other filesystems will want to call it
from other places, but there's nothing ext2-specific about it.
Make it a little more generic by allowing it to take a count of the number
of bytes to zero rather than fixing it to a single page. Thanks to Dave
Hansen for suggesting that I need to call cond_resched() if zeroing more
than one page.
