exfat: fix referencing wrong parent directory information after renaming
During renaming, the parent directory information maybe
updated. But the file/directory still references to the
old parent directory information.
This bug will cause 2 problems.
(1) The renamed file can not be written.
[10768.175172] exFAT-fs (sda1): error, failed to bmap (inode : 7afd50e4 iblock : 0, err : -5)
[10768.184285] exFAT-fs (sda1): Filesystem has been set read-only
ash: write error: Input/output error
(2) Some dentries of the renamed file/directory are not set
to deleted after removing the file/directory.
exfat_update_parent_info() is a workaround for the wrong parent
directory information being used after renaming. Now that bug is
fixed, this is no longer needed, so remove it.
