ext4: reject the 'data_err=abort' option in nojournal mode

[ Upstream commit 26343ca0 ]

data_err=abort aborts the journal on I/O errors. However, this option is
meaningless if journal is disabled, so it is rejected in nojournal mode
to reduce unnecessary checks. Also, this option is ignored upon remount.
