ovl: remove redundant IOCB_DIO_CALLER_COMP clearing

Browse Source 
The backing_file_write_iter() function, which is called
immediately after this code, already contains identical
logic to clear the IOCB_DIO_CALLER_COMP flag along with
the same explanatory comment. There is no need to duplicate
this operation in the overlayfs code.
