commit ebc4b2c1ac92fc0f8bf3f5a9c285a871d5084a6b upstream.
Function jbd2_journal_shrink_checkpoint_list() assumes that '0' is not a
valid value for transaction IDs, which is incorrect.
Furthermore, the sbi->s_fc_ineligible_tid handling also makes the same
assumption by being initialised to '0'. Fortunately, the sb flag
EXT4_MF_FC_INELIGIBLE can be used to check whether sbi->s_fc_ineligible_tid
has been previously set instead of comparing it with '0'.
