ext4: use ext4_data_block_valid() in ext4_free_blocks()
The block validity framework does a more comprehensive set of checks, and it saves object code space to use the ext4_data_block_valid() than the limited open-coded version that had been in ext4_free_blocks(). Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
