Do not set default 'before.layout' when reshaping from RAID4 to RAID4 

Commit fdcad551e9
brings some changes to reshape process.
Setting 'before.layout' when reshaping from RAID4 to another RAID4 is
not really necessary.
If reshape is restarted 'before.layout' will be compared with
'info->array.layout' in reshape_array(). Changes brought by mentioned
commit will cause this comparation return as false, becouse 'array.layout'
is always set to 'ALGORITHM_PARITY_N' in analyse_change() for RAID4, so
reshape will not be continued after reboot/stop.
This patch reverts unnecessary changes.
