ms/ext4: handle ext4_mark_inode_dirty errors
ext4_mark_inode_dirty() can fail for real reasons. Ignoring its return
value may lead ext4 to ignore real failures that would result in
corruption / crashes. Harden ext4_mark_inode_dirty error paths to fail
as soon as possible and return errors to the caller whenever
appropriate.
One of the possible scnearios when this bug could affected is that
while creating a new inode, its directory entry gets added
successfully but while writing the inode itself mark_inode_dirty
returns error which is ignored. This would result in inconsistency
that the directory entry points to a non-existent inode.
Ran gce-xfstests smoke tests and verified that there were no
regressions.

Backport notes:
* skipped hunk for ext4_handle_inode_extension(), no function in vz7
* skipped hunk for ext4_xattr_inode_write(), no function in vz7
* added an error check of ext4_mark_inode_dirty() ret code in
ext4_iomap_end()
* added an error check of ext4_mark_inode_dirty() ret code in
ext4_xattr_set_acl()
* in ext4_mark_inode_dirty() ext4_error_inode_err() has been substituted
with ext4_std_error() + ext4_error_inode()
