f2fs: do not set LOST_PINO for renamed dir
After renaming a directory, fsck could detect unmatched pino. The scenario
can be reproduced as the following:
$ mkdir /bar/subbar /foo
$ rename /bar/subbar /foo
Then fsck will report:
[ASSERT] (__chk_dots_dentries:1182) --> Bad inode number[0x3] for '..', parent parent ino is [0x4]
Rename sets LOST_PINO for old_inode. However, the flag cannot be cleared,
since dir is written back with CP. So, let's get rid of LOST_PINO for a
renamed dir and fix the pino directly at the end of rename.
