ext4: Convert callers of ext4_get_blocks() to use ext4_map_blocks() This saves a huge amount of stack space by avoiding unnecesary struct buffer_head's from being allocated on the stack. In addition, to make the code easier to understand, collapse and refactor ext4_get_block(), ext4_get_block_write(), noalloc_get_block_write(), into a single function.
