ext4: don't complain about incorrect features when probing
If mount is auto-probing for filesystem type, it will try various
filesystems in order, with the MS_SILENT flag set. We get
that flag as the silent arg to ext4_fill_super.
If we're probing (silent==1) then don't complain about feature
incompatibilities that are found if it looks like it's actually
a different valid extN type - failed probes should be silent
in this case.
If the on-disk features are unknown even to ext4, then complain.
