[0/1] PM: hibernate: Fix swap file marking

Message

It seems that the swap writer might need be flushed after marking the 
signature into the swap files, otherwise the system may power off before
the signature is written. This is what happened on my system (the swap 
file was missing the hibernation signature) and this patch allowed it
to restore from the hibernation image. 

I don't know if it might be due to a peculiarity of the system I am using,
it is a custom board with an iMX28 SoC and the hibernation image is stored
on the gpmi nand flash.

Best regards,

Laurent
