jbd2: don't load superblock in jbd2_journal_check_used_features()
Since load_superblock() has been moved to journal_init_common(), the
in-memory superblock structure is initialized and contains valid data
once the file system has a journal_t object, so it's safe to access it,
let's drop the call to journal_get_superblock() from
jbd2_journal_check_used_features() and also drop the setting/clearing of
the veirfy bit of the superblock buffer.
