[PATCH 1/4] migration/ram: only possible bit set in invalid_flags is RAM_SAVE_FLAG_COMPRESS_PAGE

[Wei Yang]

The only possible bit set in invalid_flags is
RAM_SAVE_FLAG_COMPRESS_PAGE at the beginning of function
ram_load_precopy(), which means it is not necessary to do
another check for RAM_SAVE_FLAG_COMPRESS_PAGE bit.
