ext4: ext4_put_super: Remove redundant checking for 'sbi->s_journal_bdev'
As discussed in [1], 'sbi->s_journal_bdev != sb->s_bdev' will always
become true if sbi->s_journal_bdev exists. Filesystem block device and
journal block device are both opened with 'FMODE_EXCL' mode, so these
two devices can't be same one. Then we can remove the redundant checking
'sbi->s_journal_bdev != sb->s_bdev' if 'sbi->s_journal_bdev' exists.
