ext4: return ENOMEM if sb_getblk() fails
commit 860d21e2c585f7ee8a4ecc06f474fdc33c9474f4 upstream. The only reason for sb_getblk() failing is if it can't allocate the buffer_head. So ENOMEM is more appropriate than EIO. In addition, make sure that the file system is marked as being inconsistent if sb_getblk() fails.
