f2fs: Fix the race condition of resize flag between resizefs
Because the set/clear SBI_IS_RESIZEFS flag not between any locks,
In the following case:
thread1 thread2
->ioctl(resizefs)
->set RESIZEFS flag ->ioctl(resizefs)
... ->set RESIZEFS flag
->clear RESIZEFS flag
->resizefs stream
# No RESIZEFS flag in the stream
Also before freeze_super, the resizefs not started, we should not set
the SBI_IS_RESIZEFS flag.
So move the set/clear SBI_IS_RESIZEFS flag between the cp_mutex and
gc_lock.
