David Woodhouse d96fb997c6 [JFFS2] Fix race in post-mount node checking
For a while now, we've postponed CRC-checking of data nodes to be done
by the GC thread, instead of being done while the user is waiting for
mount to finish. The GC thread would iterate through all the inodes on
the system and check each of their data nodes. It would skip over inodes
which had already been used or were already being read in by
read_inode(), because their data nodes would have been examined anyway.

However, we could sometimes reach the end of the for-each-inode loop and
still have some unchecked space left, if an inode we'd skipped was
_still_ in the process of being read. This fixes that race by actually
waiting for read_inode() to finish rather than just moving on.

Thanks to Ladislav Michl for coming up with a reproducible test case and
helping to track it down.
