xfs_repair does not zero the log in no_modify mode. In doing so, it also
skips the function that scans the log, locates the head/tail blocks and
sets the current LSN. Now that the log state is used beyond phase 2, the
log scan must occur regardless of whether no_modify mode is enabled or
not.
Update phase 2 to always execute the log scanning code. Push down the
no_modify checks into the log clearing helper such that the log is still
not modified in no_modify mode.
