ext4: check for shutdown and r/o file system in ext4_write_inode() (2018-12-19 14:36:58 -0500)

----------------------------------------------------------------
All cleanups and bug fixes; most notably, fix some problems discovered
in ext4's NFS support, and fix an ioctl (EXT4_IOC_GROUP_ADD) used by
old versions of e2fsprogs which we accidentally broke a while back.
Also fixed some error paths in ext4's quota and inline data support.
Finally, improve tail latency in jbd2's commit code.
