ext4: remove ext4_new_blocks() and call ext4_mb_new_blocks() directly
There was only one caller of the compatibility function ext4_new_blocks(), in balloc.c's ext4_alloc_blocks(). Change it to call ext4_mb_new_blocks() directly, and remove ext4_new_blocks() altogether. This cleans up the code, by removing two extra functions from the call chain, and hopefully saving some stack usage. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
