Zhang Yi 2dfba3bb40 jbd2: correct the end of the journal recovery scan range
We got a filesystem inconsistency issue below while running generic/475
I/O failure pressure test with fast_commit feature enabled.

 Symlink /p3/d3/d1c/d6c/dd6/dce/l101 (inode #132605) is invalid.

If fast_commit feature is enabled, a special fast_commit journal area is
appended to the end of the normal journal area. The journal->j_last
point to the first unused block behind the normal journal area instead
of the whole log area, and the journal->j_fc_last point to the first
unused block behind the fast_commit journal area. While doing journal
recovery, do_one_pass(PASS_SCAN) should first scan the normal journal
area and turn around to the first block once it meet journal->j_last,
but the wrap() macro misuse the journal->j_fc_last, so the recovering
could not read the next magic block (commit block perhaps) and would end
early mistakenly and missing tN and every transaction after it in the
following example. Finally, it could lead to filesystem inconsistency.

 | normal journal area                             | fast commit area |
 +-------------------------------------------------+------------------+
 | tN(rere) | tN+1 |~| tN-x |...| tN-1 | tN(front) |       ....       |
 +-------------------------------------------------+------------------+
                     /                             /                  /
                start               journal->j_last journal->j_fc_last

This patch fix it by use the correct ending journal->j_last.
