ext4: rename ext4_block_zero_page_range() to ext4_block_zero_range()

ext4: rename ext4_block_zero_page_range() to ext4_block_zero_range()

Rename ext4_block_zero_page_range() to ext4_block_zero_range() since the
"page" naming is no longer appropriate for current context. Also change
its signature to take an inode pointer instead of an address_space. This
aligns with the caller ext4_block_zero_eof() and
ext4_zero_partial_blocks().
