Subject: [PATCH -next] ext4: Fix build error while CONFIG_PRINTK is n

fs/ext4/balloc.c: In function ‘ext4_wait_block_bitmap’:
fs/ext4/balloc.c:519:3: error: implicit declaration of function ‘ext4_error_err’; did you mean ‘ext4_error’? [-Werror=implicit-function-declaration]
   ext4_error_err(sb, EIO, "Cannot read block bitmap - "
   ^~~~~~~~~~~~~~

Add missing stub helper and fix ext4_abort.

Reported-by: Hulk Robot <hulkci@...wei.com>
Fixes: 2ea2fc775321 ("ext4: save all error info in save_error_info() and drop ext4_set_errno()")
