[PATCH] migration: fix saving normal page even if it's been compressed

[guangrong.xiao@xxxxxxxxx]

From: Xiao Guangrong <xiaoguangrong@xxxxxxxxxxx>

Fix the bug introduced by da3f56cb2e767016 (migration: remove
ram_save_compressed_page()), It should be 'return' rather than
'res'

Sorry for this stupid mistake :(
