exfat: remove duplicate write inode for extending dir/file

Browse Source 
Since the timestamps need to be updated, the directory entries
will be updated by mark_inode_dirty() whether or not a new
cluster is allocated for the file or directory, so there is no
need to use __exfat_write_inode() to update the directory entries
when allocating a new cluster for a file or directory.
