f2fs: flush SIT journal during filesystem resize

Browse Source 
During a filesystem resize, SBI_IS_RESIZEFS prevents new SIT entries
from being added to the journal and forces existing entries to the SIT
area. However, f2fs_flush_sit_entries() returns early when there are no
new dirty sentries, leaving existing journal entries behind.

After the main area shrinks, a later checkpoint can access a journal
entry whose segment number is outside the new geometry and trigger
f2fs_bug_on().

Only take the zero-dirty fast path when entries may be written back to
the journal. This lets resize drain existing entries through
remove_sits_in_journal() even when there are no new dirty sentries.
