9 years agofsck.f2fs: attempt to identify bad dentries

fsck.f2fs: attempt to identify bad dentries

If a dentry has a bad ino (fsck_chk_nod_blk() fails)
and has a name len of 0, then __chk_dentries() will end up stuck:

....
[__chk_dentries: 663] [  4]-[0x0] name[] len[0x0] ino[0x5f1710dc] type[0xd1]
[ASSERT] (sanity_check_nid: 184)  --> nid is not valid. [0x5f1710dc]
[__chk_dentries: 663] [  4]-[0x0] name[] len[0x0] ino[0x5f1710dc] type[0xd1]
[ASSERT] (sanity_check_nid: 184)  --> nid is not valid. [0x5f1710dc]
[__chk_dentries: 663] [  4]-[0x0] name[] len[0x0] ino[0x5f1710dc] type[0xd1]
[ASSERT] (sanity_check_nid: 184)  --> nid is not valid. [0x5f1710dc]
....

This change tries to identify bad dentries:
 - is the ino a valid NID?
 - is the FILE_TYPE a happy type?
